Synthesis and Characterization of Chromium Doped NiSe

Nickel selenide and chromium doped Nickel selenide have been successfully synthesized. Nickel selenide nano particles has beensynthesized from the reaction of Nickel acetate [CH₃COO)₂ Ni.4H₂O] with sodium selenite (Na₂SeO₃) in the presence of glycerol as capping agent and hydrazine hydrate (N₂H₄.H₂O) as reductant at 90 ^â—‹C for 6.30 hours through simple thermal reduction process. Doped NiSe:Cr is synthesized by chemical Co-precipitation method using Nickel Chloride (NiCl₂.6H₂O), Sodium Selenite (Na₂SeO₃), Chromium Chloride (CrCl₃.6H₂O) and PVP which act as reductant and capping agent at room temperature. NiSe and doped NiSe:Cr were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), infrared spectroscopy (IR), Visible Ultra violet spectroscopy (UV), Energy dispersive X-ray spectroscopy (EDX) and photoluminescence (PL) spectra.
