Abstract
The chemical co-precipitation approach was used to make cadmium sulfide (CdS) nanoparticles in this study. The produced samples' structural, elemental composition, and morphological features were investigated. Cadmium and sulfur were obtained from cadmium chloride and thiourea. The X-ray diffraction (XRD) technique was used to determine the crystalline structure, crystal size, interplaner space, lattice parameter, unit cell volume, and microstrain caused in the lattice. At room temperature, XRD results reveal CdS hexagonal Wurtzite (WZ) structural phases. The average grain size was discovered to be in the nanometer range, confirming the existence of nanoparticles. The nanoparticles have a smooth surface and appear to be generally spherical in shape, according to FESEM micrographs, with a crystallite size of 12.76 nm. Cadmium (Cd) and Sulfur (S) are present in almost stoichiometric proportions, according to EDAX analysis. CdS are suited for optoelectronic device applications, according to the research
