Tailored Mn-doped CuS Nanoparticles: Synthesis, Structural, Optical and Thermal Characterization

Pure and Manganese(Mn) doped Covellite (CuS ) nanoparticles were synthesized by chemical precipitation method.The XRD analysis confirmed the formation of hexagonal phase for both pure and Mn doped CuS nanoparticles with average crystallite sizes 3.8 nm and 5.7 nm respectively .The Energy Dispersive Spectra(EDS) Analysis confirmed the elemental composition for pure and Mn doped CuS.Surface Morphology Analysis by Field Emission Scanning Electron Microscopy (FE-SEM) showed the formation of irregular nano flakes. The optical properties were studied by UV-visible Diffuse Reflectance Spectroscopy. Thermal behavior of pure and doped covellite nanoparticles were analyzed through TGA-DSC measurements.
