Abstract:

In this paper we discussed cost effective chemical co-precipitation method for preparing water soluble Ni doped ZnS nanoparticles and studied the effect of dopant concentration on the structural, morphological, compositional and photo luminescence properties using X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), energy dispersive analysis of X-rays (EDAX) and photo luminescence studies. Broadened XRD peaks confirmed the formation of nano-sized ZnS: Ni nanoparticles with cubic structure at different capping agent concentrations. SEM and EDAX analysis showed surface morphology and effective elemental composition of prepared nanoparticles. The Raman peak observed at 344 cm-1 can be assigned as the LO mode of cubic ZnS. Ni doped ZnS nanoparticles and showed broad emission ranging from 440-520 nm. The Photo Luminescence intensity of ZnS: Ni Nanoparticles is enhanced by the incorporation of Ni ions.
