摘要：
In the present work, conventional chemical co-precipitation method was employed for the preparation of CdS nanoparticles. XRD studies reveal that CdS crystallizes in single phase hexagonal structure. The particle size of CdS nanoparticles is obtained as 13nm. Microstructural analysis using Scanning Electron Microscope (SEM) supplemented with EDAX were carried out for the sample to find grain size as well as chemical composition. SEM study reveals that the sample consist of nanoclusters, the grains have aggregated to form clusters. A detailed systematic study on CdS sample is done by characterizing TEM, UV-VIS-NIR spectra, Photoluminescence (PL) spectra, DSC/TGA and FTIR.
