  • Abstract

    The nano crystals were synthesized by two different routes such as thermal reduction process and coprecipitation process and the difference in morphology of NiSe:Zn was studied. Zn doped nickel selenide was synthesized from the reaction of nickel chloride (NiCl2.6H2O), sodium selenite (Na2SeO3) and anhydrous zinc chloride (ZnCl2) using poly-N-Vinyl-2-pyrrolidone (PVP) as capping agent and hydrazine hydrate (N2H4. H2O) as reductant in thermal reduction process (method-1). In coprecipitation process it was prepared by the reaction of NiCl2.6H2O, Na2SeO3 and anhydrous ZnCl2 using certain amount of PVP which acts as reductant as well as capping agent (method-2). The products were characterized by x-ray diffraction (XRD), Field Emission Scanning electron microscopy (FE-SEM), Energy dispersive x-ray spectroscopy (EDX), Fourier Transform Infra red spectroscopy (FT-IR), Visible Ultra violet spectroscopy (UV) and Photoluminescence (PL) techniques.
