Abstract

We present a photoluminescence excitation study of CdSe nanocrystals embedded in a silicate glass matrix. The band edge emission was found to be strongly dependent on the excitation photon energy (hv_L) when hv_L is much higher than the fundamental absorption peak. Using the theoretical energies of electronic states in CdSe nanocrystal calculated by Ekimov et al. [J. Opt. Soc. Am. B 10, 100 (1993)] we showed our results can be understood as a size-selective effect. We also show that it is possible to use such excitation spectroscopy to determine the excited state energies and also the size distribution in nanocrystal samples.

CdS/ZnS-doped silico-phosphate films prepared by sol-gel synthesis
2018, Journal of Non-Crystalline Solids
Silico-phosphate films doped with CdS/ZnS quantum dots (QDs) for luminescence temperature sensing devices, were deposited on silicon substrate by sol-gel method, spin coating technique. Optical absorption and photoluminescence emission of CdS/ZnS-doped silico-phosphate films were investigated. CdS/ZnS nano-crystalline particles were put into evidence by X-Ray Diffraction (XRD) spectroscopy. The specific vibration modes of the constituents were evidenced by structural analysis carried out by Raman and Fourier Transform Infrared spectroscopy (FTIR). The characteristic fluorescence emission of CdS/ZnS nanoparticles was noticed in the visible domain. The morphology of the films was investigated by Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and Transmission Electron Microscopy (TEM). Clusters of hexagonal crystalline CdS/ZnS QDs were put into evidence.
Synthesis of an optically clear, flexible and stable hybrid ureasilicate matrix doped with CdSe nanoparticles produced by reverse micelles

The NPs produced by colloidal methods have many potential applications in electronics and photonics, but it becomes necessary to enclose them in a solid matrix in order to be able to produce devices for these applications [11]. Various approaches have been developed to produce thin films or monoliths doped with semiconductor NPs, including the use of polymers [12], high temperature glass [13], glassy materials by sol–gel [14], or hybrid materials also produced by sol–gel [15]. Among the hybrid materials produced by the sol–gel technique, the ureasilicates have been used for immobilizing CdS [16,17] and ZnxCd1−xS [18] NPs.
Optically clear and flexible organic–inorganic hybrid materials doped with CdSe nanoparticles (NPs) were synthesized by a sol–gel method based on the hydrolysis and condensation reactions of ureasilicate precursors. The CdSe NPs were produced by a colloidal method using reverse micelles and were then transferred to the ureasilicate precursor solution followed by gelation of the mixture using ammonia/water vapours as catalyst for the sol–gel process. The influence of the NPs surface in the dispersion of the NPs within the matrix was investigated by the addition of a capping agent with both thiol and siloxane groups (3-mercaptopropyltrimethoxysilane, MPTMS). This capping agent was used in order to improve compatibility and avoid aggregation of the NPs within the matrix and to increase the preservation of the original optical properties of the NPs. The nanocomposites obtained were characterized by absorption spectroscopy, steady-state photoluminescence, time resolved photoluminescence, HRTEM and FTIR spectroscopy. The results obtained showed the influence of the use of MPTMS in the preservation of the original optical properties of the CdSe NPs after their transfer into the ureasilicate matrix. The HRTEM analysis showed the presence of well-dispersed spherical NPs with well-defined lattice fringes. The obtained nanocomposites exhibit high transparency in the visible range as a result of the good dispersion of the NPs within the matrix, showing the potentials of the developed method in the production of composite materials in which the optical properties of the NPs incorporated are crucial to the desired application.
Optical Properties of Semiconductors
2011, Comprehensive Semiconductor Science and Technology
The optical properties of semiconductors have been studied extensively for their relevance to applications such as lasers, light-emitting diodes, and solar cells. They are also important from the basic physics point of view. In this chapter, we review some of the developments and achievements in the study of optical properties of semiconductors, including recent results in nanostructured semiconductor systems. An extensive set of references and tables of optical parameters is presented. Although the equations are displayed in cgs units in the main text, they are also given in the SI system of units in the appendix.
Photoluminescence studies on nanostructured cadmium sulfide thin films prepared by chemical bath deposition method and annealed at different temperatures
2010, Journal of Luminescence

The PL spectra in the present case arises from the size distribution. It has been reported that [43] the peak position of the PL of CdSe nanocrystals (radii of the nanodots were in the range 2.05–3.5 nm) embedded in a silica glass matrix has been observed to depend on the excitation photon energies and the phenomenon has been considered as a size selective excitation effect. In the present experiment, the observed change in PL peak position with photoexcitation wavelength, for the thin films annealed at a temperature of 250 °C or higher, is size selective photoluminescence.
Nanostructured cadmium sulfide (CdS) thin films have been prepared by chemical bath deposition (CBD) method and after post deposition annealing of the thin films at different temperatures, photoluminescence (PL) property has been studied. The effects of various photoexcitation wavelengths on the PL behaviour of different annealed films of CdS were studied by recording the PL spectra. The intensity of PL, the profile of the PL spectra and the effects of photoexcitation wavelength depend drastically on the temperature of the post deposition annealing of the thin films. The XRD patterns of the films show the presence of both the hexagonal and cubic phases (mixed phases). The emission peak arises from the surface defects of the CdS nanocrystalline thin films. Significant modification in the surface morphology of the CdS films upon annealing has been observed from the FESEM images. The morphology of the thin films is expected to influence the PL behaviour of the CdS thin films. The quantum size effect and size dependant PL have been observed.
Photoluminescence of Si nanocrystals under selective excitation
2009, Journal of Physics and Chemistry of Solids
Photoluminescence of Si nanocrystals passivated by different alkanes (hexane, octane, and tridecane) was studied at room temperature. It is shown that the emission band shape is not affected by the length of the carbon chain in the alkanes used for passivation. A pronounced fine structure of the photoluminescence band consisting of peaks separated by 150–160 meV was observed under resonant excitation. The structure is interpreted by predominant contribution from Si nanocrystal groups with particular stable size/shape existing in addition to the previously reported nanocrystals with “magic” numbers of Si atoms. The contribution of these stable nanocrystals is revealed using selective resonant photoexcitation to the higher energy states in the discrete energy spectrum of such nanocrystals.
Growth process and investigation of some physical properties of CdS nanocrystals formed in polymer matrix by successive ionic layer adsorption and reaction (SILAR) method
2007, Journal of Crystal Growth
CdS nanocrystals have been prepared successfully using successive ionic layer adsorption and reaction (SILAR) method at room temperature (26 °C) in polymer matrix. Gelatin coated on ordinary glass slide used as a matrix substrate, the nanocrystals were prepared using cadmium acetate as a cadmium ion source and sodium sulfure as a sulfure ion source. To obtain good quality of CdS nanocrystals the preparative conditions such as concentration, pH and temperature of solutions were optimized. Nanocrystals formed in gelatin matrix were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) that the structure is polycrystalline with cubic structure, of about 20 nm which aggregated in the form of polydispersive nanoclusters with sizes in the range of 10–80 nm. Optical absorption and transition study shows a blue shift in band gap energy and this shift is decrease with number of cycles. The energy dispersive X-ray analysis (EDAX) reveals the average atomic percentage of Cd:S was 59:41, showing that the preparation are almost stoichiometric.
