Abstract
A systematic study is presented on the synthesis of ZnS nanoparticles by using simple chemical precipitation method without using any capping agent. The ZnS nanoparticles have been synthesized using precursor solution with different Zn2+:S2− ratio. The as synthesized nanoparticles have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), UV–Vis absorption spectroscopy and impedance spectroscopy. The XRD patterns reveal the formation of ZnS nanoparticles with wurtzite hexagonal phase which changes to sphalarite phase for higher concentration of S2− in the precursor solution. XRD, SEM and AFM studies have shown enhancement in particle size on increasing sulphur content. SEM and AFM images depict formation of deformed spherical nanoparticles with particle size ranging from 10 to 50 nm. Optical absorption spectra of synthesized material show a red shift in the optical absorption on increase of S2− ion concentration. Variation in electrical conductivity obtained from impedance measurements at different temperatures has been suitably correlated to Davis–Mott model.
