About The International Year of Light 2015
The International Year of Light and Light-Based Technologies (IYL 2015) is a global
initiative that will highlight to the citizens of the world the importance of light and optical
technologies in their lives and for the development of society. There has never been an international
year so multidisciplinary in its scope, including science, technology, nature and culture, and cosponsored by 35 countries around the world. A resolution declaring 2015 the International Year of
Light was passed by the full United Nations General Assembly on 20 December 2013.
The international steering committee of IYL 2015 announces the setting-up of an International
the optics contributions of Arab scholars in the
Islamic golden age, in particular the work of Ibn Al Haytham (Alhazen). The year 2015 was chosen
because it marks several significant milestones including, for instance, the one-thousandth year
anniversary of the appearance of the seven-volume treatise on optics Kitab al-Manathir, by Ibn allight. Prof. Azzedine Boudrioua, Coordinator of the WG Ibn Al Haytham, will give a talk regarding
the best ways to celebrate the contribution of Ibn Al Haytham and Arab Scholars to optics as a special
quest of AMOP2015 meeting.
As part of the International Year of Light 2015, a special session shall be presented at Saudi
Physical Society, Atomic Molecular and Optical Physics (AMOP) second Annual Meeting sponsored
by Saudi Physical Society and the Aljouf University Physics Department on 31 March-1 April and
celebrated under the auspices of UNESCO. This component will be featuring exciting demonstrations
regarding light and fascinating presentations at a popular science level offered by world-class
scientists visiting Aljouf University both from other Saudi institutions and from around the world. As
far as we are aware, this is second major event in Saudi Arabia after SIMFP2015 meeting took place
on 17-19 February, 2015 at Jazan University, KSA.

The United Nations declared 2015 the International Year of Light. In its resolution the UN emphasize
the importance of light and Light-based Technologies based in the lives of the citizens of the world
and the future development of human society. They also emphasize the coincidence of this event with
the anniversary of many important milestones in the history of science of light from the
groundbreaking work of Ibn al Haytham in 1015 to Einstein's theories on the photoelectric effect in
1905 and on the relationship between light and cosmology highlighted by general relativity in 1915,
and the discovery of the cosmic microwave background by Penzias and Wilson as well as Kao's work
on optical transmission.
The development of optics as a scientific and technological discipline foreground is practically made
during the last quarter of the 20th century. Early work on optics are attributed to the School of
Alexandria, Euclid (325 - 265, Av JC.). However, the reform of optics was undertaken by Muslim
Scholars of the medieval period with at their head Al-Kindi (801-873) and especially Ibn al-Haytham
known as Alhazen (965-1040). This illustrious scientist has really laid the foundations of modern
optics with its experimental approach to light propagation. He, in fact, introduced experimentation in
physics and provided the basis for understanding the phenomena related to light propagation. The
legacy of this eminent scientist was transmitted to us especially through his major work 'Kitab alManazir' (Book of Optics), which was translated into Latin and published in the West in the early 13 th
century. This book has influenced the work on optics of most Renaissance Scholars.
This presentation will provide an overview of the evolution of optics with a focus on the work of Ibn
al Haytham and its impact on the development optics as a modern science.

This presentation gives a brief showcase on the significance of light - the light that makes the world
beautiful, light from celestial bodies, sunlight and life on the earth, the wonderful laser, light as the
career of information, and information communication technology that has brought a new revolution
in our own lives. It is with this background that we present here a brief history of our understanding of
light, starting from the early Egyptian era to the modern period. It covers the mystery of 'light and
darkness', the basic properties of light, namely, rectilinear propagation, reflection and refraction, light
and vision, and the speed of light. Their study by the philosophers and scientists of the Greek period,
followed by those of the Golden Age of Arab Science, are briefly mentioned. The pioneering
contributions of Ibn al-Haytham in optics 1000 years back, formed the basis of modern optics and
opened the new gateway for further researches by Europeans about 650 years later. The Newton's
refraction experiment on white light passing through a prism was the first such important work. After
the corpuscular theory of light was found unsuccessful in explaining certain optical phenomena, the
wave theory of light remained in place till the late 19th century. Albert Einstein's explanation of the
photoelectric effect in 1905, establishing the particle nature of light, finally paved the way for its dual
characteristics. This is followed by the 'laser' - the wonderful light, which has enormous applications
and has opened up entirely new areas of research. Finally, the use of Information Communication
Technology in Education is briefly discussed, which drives its strength from researches on light, along
with certain ideas for achieving the IYL2015 objectives.

The year 2015 has been declared as the International Year of Light by UNESCO in recognition of
several important milestones in our understanding of light and vision going back to ancient times. One
such milestone is the 1000 year anniversary of the first ever book on light Kitab al-Manazir by ibn alHaytham. For many early thinkers and natural philosophers, optics was considered the most
fundamental of the natural sciences. Human efforts to understand vision and the nature of light
remained at the forefront of intellectual endeavors for about two thousand years. A study of optics in
the Western and Islamic cultures provides an understanding of the intellectual growth of these
societies. This talk will attempt to retrace some of this history.

ENGINE CYCLES WITH CASIMIR FORCES: OPEN ISSUES, EXPERIMENTS,

Casimir forces are, generally, a consequence of the introduction of boundaries into any free field. They
exist in classical acoustic fields, and in the Dirac and gluon fields, thus affecting nucleon masses. In
the particular case of the electromagnetic field, such effects are determined by the contrast of dielectric
functions at interfaces so that, by modifying the optical properties of materials, it is possible to
manipulate Casimir forces. Although this appears obvious today, the path leading to the realization
that Casimir forces can be modulated has been long. A single paper published by a German group over
thirty years ago contained, for over two decades, the only available theoretical estimates and
experimental results. However, such a small beginning may have spurred research leading to the
development of an entirely new industry potentially capable to transform our lives as thoroughly as
happened with the invention of integrated transistors. We briefly review the history leading to the
Casimir-Lifshitz theory of dispersion forces, we obtain useful order-of-magnitude estimates, and we
rapidly move on to consider mechanisms for Casimir force-based engine cycles. This leads us to
consider ground-breaking experiments, follow up studies with different approaches, and the
experimental effort presently being carried out at Jazan University. We analyze persistent
disagreements between theory and experiment, and amongst various researchers, as to the behavior of
Casimir forces in excited matter. Since Casimir forces diverge as a negative high power of the
interboundary gap, all such issues become of critical importance on the nanoscale with corresponding
particle accelerations among the largest possible in nature. Finally, we consider technology transfer of
such cutting edge quantum electrodynamics knowledge into novel devices and the equally fascinating
interaction between physics, Silicon Valley, the world of international venture capital investments and
the marketplace potentially poised to also benefit the Kingdom.

In this work, Silver (Ag) metal nano particles were produced from silver metal target via pulsed laser
ablation in liquid (PLAL) and were used to doped with Zinc oxide (ZnO) nano-rods via the same
technique in order to shift the band gap to the visible spectral region. The UV-vis absorbance spectrum
of the synthesized Ag-ZnO nano-composite confirms that the absorbance peak has shifted from 386
nm to 410 nm after pulsed laser ablation. The structural property of the synthesized Ag-ZnO
composite was investigated using XRD technique which shows development of new diffraction peak
due to development of new planes after the laser ablation. The Scanning electron microscope (SEM)
image of the synthesized composite after ablation was obtained which confirms that a core-shell
structure was achieved between the Ag and ZnO nanoparticles. In a higher resolution micrograph of
the Ag-ZnO composite, the TEM image of the composite shows clearly that the particles size of the
composite becomes smaller and a core shell appeared between the ZnO and Ag nano-particles.
Selected area electron diffraction (SAED) exhibits that the composite becomes polycrystalline due to
the development of more crystals planes which confirms the new peaks developed in the XRD
analysis. In summary, a core shell Ag-ZnO nanocomposite was successfully synthesized via pulse
laser ablation in liquid with no impurity as confirmed with the EDS spectra.

Laser-based sensing has attracted great interest recently due to several advantages such as high
sensitivity and specificity, large dynamic range, multi-component capability, and lack of pretreatment
or preconcentration requirements. The availability of broadly tunable sources like difference frequency
generation (DFG) and external cavity quantum cascade lasers (EC-QCLs) or the most recent
development of diode-pumped lead salt vertical external cavity surface emitting lasers (VECSELs) has
certainly eased the implementation of laser-based sensing devices. I shall discuss the basic principles,
present various experimental setups and illustrate the performance of systems developed in our
laboratory.
Multi-component capability is demonstrated with a CO2-laser based mobile system applied to road
traffic measurements. Recent measurements with a mid-IR VECSEL enable the fast analysis of C 1-C4
alkanes at sub-ppm concentrations in gas mixtures which is of interest for the petrochemical industry.
In human breath the D/H ratio has been determined after intake of a small amount of D 2O as a tracer.
An enhanced deuterium content in the breath could be recorded during a month. Such data can be used
to determine the total body water, energy expenditure, glucose or cholesterol synthesis rates. Spectra
of surgical smoke
produced and collected during minimal-invasive surgery with an electro-knife in
the University hospital in Zurich
have been recorded with a broadly tunable DFG system and
analysed with a principal component analysis. Besides water vapor, mainly traces of methane, ethane,
ethylene, CO and the anesthetic gas sevoflurane were found. Finally, studies in the area of medical
diagnosis were performed with a fiber-coupled EC-QCL photoacoustic system to measure glucose in
human skin. During in vivo oral glucose tolerance tests with volunteers, comparisons were made with
conventional blood glucose measurements with a glucometer. Although first results of the noninvasive laser-photoacoustic method look promising further developments are still needed.

consent seriously compromises the secrecy of correspondence, which is a very intimate issue in the
modern world. Classical communication systems cannot guarantee the security of communication
against unwanted location tracking, because the sender must broadcast a signal at the moment of
sending the message. The source of the signal could be always located, at least in principle. Quantum
communication, however, enables sending the message with pre-distributed entangled quantum
systems, specific local weak measurements, time synchronization between the sender and the receiver
and classical communication by the message receiver alone. In contrast to all early suggested quantum
communication schemes, the correlation of the measurement results at the sender's and the receiver's
stations, which is necessary for information transmission in accordance with no-communication
principle, is achieved by synchronization of local measurement times and two types of local weak
measurements assisted with classical information transmission by the receiver alone. While the sender
never broadcasts a classical signal, any possibility of their unpermitted positioning is prevented.

Slow light with electromagnetically induced transparency (EIT) in the core of cylindrical waveguide
(CW) for an optical fiber system containing three-level atoms is investigated. The CW modes are
treated in the weakly guiding approximation which renders the analysis into manageable form. The
transparency window and permittivity profile of the waveguide due to the strong pump field in the EIT
scheme is calculated. For a specific permittivity profile of the waveguide due to EIT, the propagation
constant of the weak signaled and spatial shape of fundamental guided mode are calculated by solving
the vector wave equation using the finite difference method. It is found that the transparency window
and slow light field can be controlled via the CW parameters. The reduced group velocity of slow light
in this configuration is useful for many technological applications such as optical memories, effective
control of single photon fields, optical buffer and delay line.

Dye-sensitized solar cells (DSSCs) have been considered as one of the most promising new generation
solar cells. Enormous research efforts have been invested to improve the efficiency of solar energy
conversion which is determined by the light harvesting efficiency, electron injection efficiency and
undesirable electron lifetime. A simple, cheap and trustable laser-induced photovoltage and
photocurrent decay (LIPVCD) technique is adopted in this work in order to determine the electron

in DSSCs. In LIPVCD technique, DSSC is illuminated by a
small squared intensity-modulated laser beam. Time-based response of the DSSC is recorded using a
transient digitized oscilloscope for further analysis. Sensitization dye used studied DSSCs has an
absorption wavelength peak at 532 nm which is obtainable using a proper laser diode. Present
LIPVCD technique, using single wavelength, is tested with standard solar cells to give comparable
results with other standard techniques (i.e. IMVS, IMPS and OCVD).
Measurements are performed at open-circuit and short-circuit for a variety of DSSCs, so that the
photovoltage and photocurrent decay data are acquired and interpreted in the time domain. Studied
DSSCs are fabricated with various electrodes include TiO 2 nanoparticles and ZnO nanowire based

g )
(Y=Li,
Na, K, Rb and Cs) in its equilibrium distance and rare gas atoms. The overall potential energy is
determined by partitioning the system into two cores Y+, n
electron. The interaction between the electron and the rest of the system is computed ab-initio using
non-empirical pseudo-potentials for the Y+ core and rare gas atoms. The remaining part of the
potential energy is modelled as a sum of pairwise interactions, with the Y+-Gr contribution taken from
an ab-initio
-Toennies form and the Gr-Gr interaction as a
Lennard-Jones empirical potential. The structural and spectroscopic properties of the single rare gas
atom cluster are investigated for an extensive range of the remaining two Jacobi coordinates,
The structure and stability of the Y2+Grn clusters are then determined by exploring their potential
energy surfaces for di erent symmetries. We find that the most stable isomers are C (11), D h(21),
C2v(31), D2h(41), C3v(51) and D3h(61). To our knowledge,

USE OF X-RAY FLUORESCENCE FOR ANALYSIS OF GOLD

The aim of the present work was to develop a fast and accurate method for the analysis of gold
jewellery and gold lump pieces for the determination of their carat value, using the technique of x-ray
fluorescence (XRF). It was found that the Sudanese Standards and Metrology Organization (SSMO) is
using a conventional method for the determination of carat content of gold jewellery and gold lump
pieces. The method used by SSMO is based on scratching the gold jewellery and gold lump pieces, as
well as a gold standard, by a stone. Thereafter they drop some acid on the scratched area and they
watch for the change of colour. If the colour does not change then the gold sample under test has the
same carat value as the standard. If the colour changes then it is not of the same carat as the standard.
It was observed that the method takes a long time to perform (about an hour per sample) and it is not
accurate enough.
In the present work two methods were used for the analysis of gold jewellery and gold lump pieces by
the XRF technique. Use was made of the same gold standards employed by SSMO, namely the carats:
12, 14, 18 and 21 (which were borrowed from them). It is known that gold carats are based on the
quantity of copper and other impurities that are mixed with gold. In the present study use was made of
the ratio of K X-ray intensity emitted by copper to the L X-ray intensity emitted by gold, for the
determination of the carat value. Such ratios were measured for the four gold standards obtained from
SSMO. Then calibration curves were drawn from the obtained results, and they were then applied for
the determination of carat values of unknown gold samples. In this way it was possible to develop a
fast and more accurate method for the analysis of gold jewellery and gold lump pieces of unknown
carat value. The method was applied to a number of gold jewellery pieces of unknown carat value. The
results obtained showed a general agreement between the two methods under study days.
The developed method for the analysis of gold jewellery and gold lump pieces has the advantage of
being faster (with an analysis time of about 2 or 3 minutes per sample), and more accurate as
compared to the conventional method used by SSMO.

In optical lithography, the feature size in which scientists can write the circuits is limited to half the
wavelength of the light by something called the diffraction limit. Many attempts have been made to
advance this field beyond the current limit set by the wavelength of the laser used. In this talk, I shall
review these methods and then present a method for optical sub-wavelength lithography based on Rabi
oscillations that is only a single preparation step away from the currently implemented lithographic
process. This method allows, in principle, to write a pattern with accuracy better than a millionth of
the wavelength of the light used. We shall discuss the experimental realization of this scheme. Another
high-resolution method, the structured illumination microscopy (SIM) has been of special interest in
high precision imaging in recent years. Linear SIM has been realized nearly 20 years ago but with
resolution limitation. Since these years, nonlinear SIM has become a widely used method to get a
high-resolution image. In this talk we will discuss how the nonlinearity associated with Rabi
oscillations can be used for precision imaging.

Creation of quantum memory (QM) devices promises to be basic platform for elaboration of quantum
information technologies including universal quantum computer and long distance quantum communications.
The photon/spin echo approach [1,2] has demonstrated cogent advantages in the current researches by the
flexible possibilities in multi-mode storage [3] and recently demonstrated record quantum efficiency [4]. In spite
of the significant progress, the practically sound photon/spin echo QM schemes require further improvement of
long-lived storage and integration of the QM schemes into the quantum processing etc. Here, we present our
recent results aimed to the solution of these problems.
Electron-nuclei spin systems seem to be the most promising tool for realization of the long-lived quantum
storage. For realization of this approach in photon/spin QM technique, here, we present a new method
implementing longer QM life-time on the condensed nuclei spin ensemble characterized by the dipole-dipole
interactions and considerable inhomogeneous broadening of the resonant line. We have elaborated new radiofrequency pulse sequence providing efficient averaging of the decoherent effects in this nuclei spin ensemble [5].
We have used the general Hamiltonian approach for description of nuclei spin dynamics during the proposed
multi-pulse sequence and have demonstrated the observed advantages for faster averaging of the decoherent
effects in comparison with the well-known pulse sequences used for dynamical decoupling (DD) of the multispin systems.
Then we present experimental results on the spin echo QM protocol on the electron-nuclei spin system with
spin frequency comb (SFC) structure of the resonant transition [6]. Here, we have demonstrated the storage of
multi-pulse microwave fields at room temperature and prolongation of the QM life-time due to DD-technique.
Also we have demonstrated on-demand retrieval in the controlled gradient magnetic field. The obtained results
are discussed for potential realization in inorganic crystals doped by with rare-earth ions.
We have also presented a new scheme for implementation of the quantum random access memory based on
the impedance photon echo QM controlled by the three-level atom [7]. Here, we describe the physical conditions
providing efficient quantum control of the photonic qubit storage. Finally we have discussed the possible
implementations of this scheme by using the optical and microwave technique.

This work offers a mathematical model to simulate a process of Enhanced Stimulated Raman
Scattering (ESRS). This process occurs when the exciting laser energy is above the dissociation limit
of the Raman medium. It is experimentally observed that in this condition the normal SRS lines are
enhanced with the assistance of atomic lines emission. Hence, amplification of selected Stokes lines is
observed. The proposed model was applied to the Raman medium of H 2 gas, using the fourth
harmonic of the Nd:YAG laser, 266 nm, as a laser excitation source which its energy is above the
dissociation limit of H2 gas. A comparison between simulated and experimental results was
undertaken which showed good agreement. This concluded that the proposed model, which took
stimulated emission into consideration, was a good explanation for the high conversion efficiency of
some Stokes lines. It also aided in the understanding of the enhancement process.

These last decades, optical telecommunications have made a spectacular success thanks to the
explosion of Internet. This development is the fruit of a main effort of research and development in the
field of guided optics which led to the improvement of the performances of optical fibers and
optoelectronic components able to generate, detect, modulate or commutate light. Consequently,
optoelectronic components of any kind at low cost become available in the market pushing the
emergence of other applications in various fields.
As a matter of fact, today the use of optics includes strategic fields like space and military ones and
also fields of everyday life like data storage (CD and DVD), medicine and unsuspected sectors such as
car industry.
In a competing way, the advent of Nano-Photonics is pushing the limits of photonic devices
miniaturization on scales lower than the wavelength. The interest of using the photon rather than the
electron comes from the very high optical frequencies of the optical signal which allow a very broad
band-width and offer an unequalled data transmission capacity.
Ultimately, the 20th century was the century of electronics and the 21st century is expected to be that of
photonics.
This presentation will give a highlight of the main concepts and the recent development of photonics
technology.

Laser-induced breakdown spectroscopy (LIBS) is one of the analytical techniques which have vast
application in the material analysis [1,2]. We have applied the technique for the elemental analysis to
find impurities and hazardous elements in polystyrene, polycarbonate, polyvinylchloride and poly
(methyl methacrylate) Polymers materials from one of the Saudi industries which are being used in
manufacturing of water and food containers. The aim was to identify the harmful elements present in
these polymers.
The study was carried out in high vacuum chamber. Q-switched pulsed Nd:YAG laser was used to
generate the plasma of the sample placed on rotating stage in the vacuum chamber. The emitted light
from the plasma was collected with Optical fiber and spectra were recorded after passing the light
through the spectrometer equipped with ICCD camera.
We have identified Al, Si, P, Ca, Mg, N elements in Polystyrene, Br, Mg, Ca, N in polycarbonate, Mg,
N, C in polyvinylchloride and Ca, Mg, C, N in methyl methacrylate polymer samples. We have also
detected molecular lines of CN, CO, C2 and CH in these samples. Presence of Al, Si, and P might be
harmful to the human body. LIBS is found to be simple and cost effective method to identify the
hazardous element. The industries can adopt this technique to provide harmless container for water or
food products.

Various applications of metal oxide nano-materials like Al2O3 in industry and other areas attracted a
growing interest to the synthesis of materials which are cheap and chemically highly active. Pulsed
laser ablation in liquids is a technique for synthesis of nano-particles of high purity without the use of
any expensive instrumentation. In this work, Pulsed laser ablation technique was used to synthesize
aluminium oxide (Al2O3) nano-particles from solid aluminum target in de-ionized water. A Qswitched Nd: YAG laser beam of 532 nm wavelengths having 6 ns pulse width, laser fluence of 450
mJ/cm2 and 10 Hz frequency was used as an excitation source. Al 2O3 nano-particles synthesized were
deposited on a silicon glass substrate and heated to produce thin films of alumina nano particles. These
films were then heated at temperatures of 700, 800, 900, 950, 1000, 1025, 1050, 1100 and 1230 0C
respectively to study the phase transition of Al2O3 from
Al2O3 to
Al2O3. The single-phased
Al2O3 nano particles were obtained after heating it at a temperature of 1230 C for 2 hours. The
morphological and optical characterizations techniques like XRD, HRTEM, SEM and XPS were
employed to study the evolution of crystalline phases of Al2O3 nano-particles. With these analyses, we
observed the identification of three steps on the phase transition of
Al2O3 to
Al2O3. In
summary, the size of Al2O3 nano-particles prepared by pulsed laser ablation technique in liquid was
evaluated and the relationship between the phase transitions and temperature was studied.
Key words: Phase transition, pulsed laser ablation, nanoparticles, Al2O3, XRD, crystalline phase.

Pair correlations of two dipole emitters in a finite ordered charge-sheet structure (FCSS) are
investigated. The FCSS consists of a finite number of charge sheets separating dielectric layers. The
dispersion relation and the corresponding field distributions of a general structure are determined
using transfer-matrix techniques. Firstly, we evaluate the de-excitation rate of a single dipole emitter
coupled to the quantized fields supported by such a structure. The de-excitation rate is calculated for
different numbers of charge sheets, varying excitation frequency, and varying emitter position.
Secondly, we analyse the pair correlations involving two dipole emitters localized within the FCSS.
The rates of de-excitation corresponding to a pair of states, namely symmetric state and antisymmetric state, are evaluated. The analysis is performed for different dipole orientation, their
positions in the structure and the parameters effect of FCSS. This study of field-matter interactions in
the FCSS is useful for a development of quantum-information processing and the realization of
quantum-computing.
Keywords : charge-sheet structure, de-excitation rate, dipole emitter, pair correlations

In the present study, Osteosarcoma (U2OS) cell line was used to see the possible effects of manganese
di-oxide nanowires (MnO2 NWs) individually and their complexed forms using different types of
-Aminolevulinic acid (5-ALA), and protoporphyrin IX (Pp IX).
Cellular toxicity was detected by reactive oxygen species (ROS) which are estimated with
fluorescence spectroscopy and MTT assay under ultraviolet (UV), visible light and different laser
exposures. It is also confirmed by cellular morphology. Prominent cell debris was found with the
above nanomaterials in their complexed forms using different photosensitizer in labelled U2OS cells.
This cell death might be due to the release of singlet oxygen species in Osteosarcoma cells which is an
indication of their anticancer-cell effects.
Keywords: Osteosarcoma cell, reactive oxygen species (ROS), MTT assay, photodynamic therapy

In this paper, we studied the spectral analysis and plasma characterization of commercial polystyrene
polymer using the laser-induced plasma spectroscopy (LIPS) technique. This study was performed
using the fundamental wavelength of Nd:YAG laser at 225mJ energy and 7 ns pulse width, focused
normal to the surface of the sample under atmospherics pressure. The LIPS spectral intensities were
observed for atomic and molecular lines. The generated polymer plasma plume was monitored with
gated CCD camera and the emission was analyzed using 7 Czerny-Turner Spectrographs. By
characterization the observed plasma, the generated plasma temperature was found to be ~ 6000 K
while plasma density reached ~ 4 x 1017 cm-3. Quantitative analysis of sodium as trace element was
performed for polystyrene polymer. By optimizing the LIPS experimental condition at detection delay
time of 2 microseconds, the calibration curves for Na as minor element were achieved with linear
regression coefficient of 94 % for polymer samples at 588.9 nm. A low limit of detection LOD of
LIPS attained with a value of 0.35 ppm for sodium in the polymer samples. From the application
viewpoint, improving LIPS LOD is very important and can be easily used for monitoring the on-line
industrial production of commercial polymers for trace elements that may have risk to human health.

The novel idea to use single atoms as highly-reflecting mirrors has recently gained much attention.
Usually, in order to observe the reflective nature of an atom, it is required to couple the atom to an
external medium such that a directional spontaneous emission could be realized [1]. We propose an
alternative way to achieve the directional emission by considering a system of correlated atoms in free
space. It is well known that mutually interacting atoms have a strong tendency to emit the radiation
along particular discrete directions [2]. This relieves one from the stingy condition of associating the
atomic system to another media and facilitates the experimental implementation to a large degree.
Moreover, realistic 3-dimensional collective emission can be taken into account in the dynamics. Two
interesting spatial setups have been considered; one where a probe atom is confined in a linear cavity
formed by two atomic mirrors and, the other where a probe atom faces a chain of correlated atoms. We
observe an evidence of the mirror-like effect in a simple system of a chain of three atoms. The angular
distribution of the radiation intensity observed in the far field is greatly affected by the atomic
interactions [3]. Hence suitable directions for enhanced reflectivity can be determined.

In the present research, we have fabricated Cadmium Selenide (CdSe) quantum dots (QDs) by using a
chemical method at different, concentrations of trioctylphosphine oxide (TOPO).
After fabrication process, the cleaning process could not remove many residual chemicals. In order to
find these remained impurities in the fabricated QDs, elemental analysis is required. We have chosen
laser induce breakdown spectroscopy (LIBS) technique for the analysis due to it needs no sample
preparation or modifications, easy for analysis and cost effectiveness.
The qualitative LIBS analysis for CdSe QDs revealed that the sample contains Cd, Te, Se, H, P, Ar, O,
Ni, C, Al and He impurities. These observed results gave precise details of the impurities present in
the QDs sample. These impurities are important for future work at which controlling the impurity
contents in the QDs samples may improve the physical, optical and electrical properties of the QDs
used for solar cell application.
