Luminescence properties of Mn and Ni doped ZnS nanoparticles synthesized by capping agent

ZnS and transition metal (Mn and Ni) doped ZnS were synthesized by a simple chemical method using alkyl hydroxyl ethyl dimethyl ammonium chloride (HY) as capping agent. The structural and optical properties were studied using various techniques. FTIR and X-ray diffraction (XRD) can be used to identi...

Description
Summary:ZnS and transition metal (Mn and Ni) doped ZnS were synthesized by a simple chemical method using alkyl hydroxyl ethyl dimethyl ammonium chloride (HY) as capping agent. The structural and optical properties were studied using various techniques. FTIR and X-ray diffraction (XRD) can be used to identify the chemical bonding and crystal structure. The XRD analysis show that the particles are in cubic structure. The mean size of the nanoparticles calculated through Scherrer equation is in the range of 5–2.5 nm. Elemental dispersive analysis of doped samples reveals the presence of doping ions. The transmission electron microscopic studies show that the synthesized particles are in spherical shape. Optical characterization of both undoped and doped samples was carried out by ultraviolet–visible and photoluminescence spectroscopy. The absorption spectra of all the samples are blue shifted from the bulk ZnS.
