We studied CdS(1-x)Se(x) nanocrystals embedded in a silicate glass by means of complementary techniques like high resolution transmission electron microscopy (HRTEM), micro-Raman spectroscopy and optical transmission and reflectivity. Transmission Electron Microscopy gives complete information on crystallization and size distribution of the nanocrystals wile Raman scattering is particularly useful in the determination of the composition of the nanocrystals for low-concentration or small-crystallite size composite. Having the size distribution and composition of the nanocrystals we have explained the transmission spectra of the studied samples. Optical transmission spectra evidence the quantization of the electronic states of the nanoparticles system with a size distribution described by a Gaussian function.

Abstract

We studied CdS(1-x)Se(x) nanocrystals embedded in a silicate glass by means of complementary techniques like high resolution transmission electron microscopy (HRTEM), micro-Raman spectroscopy and optical transmission and reflectivity. Transmission Electron Microscopy gives complete information on crystallization and size distribution of the nanocrystals wile Raman scattering is particularly useful in the determination of the composition of the nanocrystals for low-concentration or small-crystallite size composite. Having the size distribution and composition of the nanocrystals we have explained the transmission spectra of the studied samples. Optical transmission spectra evidence the quantization of the electronic states of the nanoparticles system with a size distribution described by a Gaussian function.

Materials Science and Engineering is concerned with admixtures of matter or the basic matter from which products are made. The category covers ceramics, paper and wood products, polymers, textiles, composites, coatings & films, and biomaterials. Other areas covered in this category include Materials Chemistry, the application of chemistry to materials design and testing; Condensed Matter/Solid State Physics, the branch of physics concerned with the structure and properties of condensed matter (superconductors, semiconductors, ferroelectrics, and dielectrics); and Physical Chemistry/Chemical Physics, the application of the concepts and laws of physics to chemical phenomena.
