Synthesis and characterization of CuS nanocomposites by using alumina channel-technique

Abstract

CuS nanocomposites synthesized using Alumina crystallite as the medium. A core shell nanostructure developed by suitable oxidation of the composite. X ray diffraction (XRD) of synthesized CuS nanocomposites revealed the presence of two crystal structures: one is tetragonal and the other is monoclinic. All salient diffraction peaks can be closely matched to the monoclinic and tetragonal structures. The PL spectrum of the CuS nanopartic;les shows a peak centered at 410nm and 460 nm which is shorter than submicron CuS , indicating a CuS nanocrystals obtain in this work in quantum size. Materials exhibited good electrical and optical properties. Due to high dielectric constant and photo luminescence property this CuS nanocomposites can be used in different electronic and optical devices.
