Abstract

Semiconductor nanoparticles are very attractive & interesting objects for scientific research of strongly confinement effects & tailoring of band gap. Semiconductor nanocrystallites will dominate in future generation of electronic devices and growth of science and technology. Among the various materials used for fabrication, cadmium sulphide (CdS) nanoparticles have drawn much attention because of its potential application and variety of methods of its preparation.. The most important information to be obtained from growth analysis concerns the sizes, the size distribution, stoichiometry, structure and the interface configuration of the nanocrystals. Formations of nanoparticles have been characterized using various sophisticated instruments like double beam spectrophotometer, X-Ray diffraction (XRD) and Transmission Electron Microscope (TEM). Surface morphology & composition have been observed by SEM, Atomic Force Microscope (AFM) and XRF technique. Formation of bonds was examined by FTIR. Determination of size and composition observed from various characterization techniques have shown that nanoparticles size is less than 6 nm.
