Abstract
Cu and Fe doped ZnS were synthesized by a co-precipitation method using alkyl hydroxyl ethyl dimethyl ammonium chloride (HY) as capping agent. The influence of doping on the optical properties of ZnS:Cu2+ and ZnS:Fe2+ nanoparticles was investigated. The X-ray diffraction (XRD) analysis show that the particles are in cubic structure. The average particle size of the nanoparticles calculated from peak broadening of XRD pattern 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. The absorption spectra of all the doped samples are blue shifted as compared with of the undoped ZnS samples. The Pl intensity of doped ZnS nanoparticles was decreased with increasing the amount of doping Cu2+ and Fe2+ into ZnS matrix.
