Preparation and Characterization of CuS Nanoparticles Prepared by Two-Phase Colloidal Method

Abstract

Abstract In this paper, two-phase colloidal method was employed to synthesis CuS nanoparticles with different Cu : S ratios. The characterization of prepared CuS involves structural, morphological and optical properties analysis. X-Ray Diffractometer indicate that the covellite CuS have hexagonal structure. Field Emission Scanning Electron Microscope showed the formation of spherical nanostructure of CuS. UV-Visible Spectrophotometer showed the two absorption peaks of CuS nanoparticles one at UV-Visible region and the second at near infra-red region and the energy gap increase with sulfur content.
