Abstract
Copper sulphide nano materials possess different applications, such as p-type semiconductors in solar cells, optical filters, super ionic material, photo-voltaic applications, microwave shielding coatings and in combined photo acoustic imaging. In present study, copper sulphide (CuS) nano particles were synthesized by wet chemical co-precipitation method using CuCl2 and Na2S as precursors. The synthesized CuS nano particles were characterized by powder XRD, FT-IR and thermo-gravimetriy. From the powder XRD, the hexagonal crystal structure was found and the average particle size was estimated to be 10.5 nm by using Scherrer’s formula. The FTIR spectral study confirmed the presence of S-O stretching, O-H bending, and S-S disulphide stretching vibrations. The Thermal Analysis was carried out from room temperature to 700°C. The nano-particles remained stable up to 160°
