Structural and optical properties of pure and Cu2+ doped CdS nanoparticles

The synthesis of semiconductor nanoparticles was widely studied in the field of optical devices for their potential usage. These semi conductor nanoparticles are doped with transition metal(TM) ions have wide attention due to the outstanding luminescent properties. The pure cadmium sulphide (CdS) and the transition metal Cu2+ ion doped with the nanoparticles (CdS: Cu2+) are synthesised by the microwave enhanced solvothermal method. The cadmium acetate was used as cadmium source, thioacetamide as the sulphide source, and the ethylene glycol was used as the solvent for the synthesis of Cds: Cu2+. XRD pattern of Pure CdS shows cubic structure. The prepared nanocrystals were characterized by power XRD, SEM, EDAX, FTIR and UV-VIS of the samples were recorded and discussed briefly.
