Microstructural and Optical Properties of Ni doped CdS Nanoparticles Synthesized by Sol Gel route

The nanoparticles of pure and Ni doped CdS were synthesized by sol gel route in aqueous medium. The obtained particles were characterized by X-ray diffraction studies (XRD). The results of structural characterization show the formation of pure and Ni doped CdS nanoparticles in single phase without any impurity. The morphological analysis was carried out by high resolution (TEM) studies. The optical absorption spectra of pure and doped sample recorded by UV-VIS spectrophotometer in the range of 350 to 800 nm have been presented and explained. The energy band gap as calculated by the Tauc relationship was found to increase with Ni doping. Ni doped CdS may found its major applications in solar cell, sensors and photo catalysis.
