Abstract
CdS is an important material of low cost photovoltaic devices. Use of capping agents during synthesis of nanomaterials has drawn a lot of attention due to their size dependent properties. Here we reported the synthesis of CdS nanoparticles using a simple chemical precipitation method at 40°C to 70°C. The reaction was carried out at constant temperature in aqueous medium with stirring. The hydrazine hydrate was used as capping agent. The as prepared samples were characterized using X-ray powder diffraction (XRD) technique for structural analysis. The effects of growth temperature on structural properties are evaluated. The lattice strain, crystallite size and dislocation densities were calculated using the Williamson-Hall (W-H) method. The results show that the crystallite size decreases with increase in growth temperature.
