Abstract
The ZnS semiconducting nano particles were synthesized by solid state reaction method using Zinc acetate dehydrate and sodium sulfide as precursors at room temperature. The as-prepared ZnS nanoparticles have average particle size of 11 nm. Strain and the dislocation density were estimated by Stokes-Wilson formula. The structural features, chemical composition and optical properties of the nanoparticles were investigated by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infra Red Spectroscopy (FTIR), Ultra Violet spectroscopy (UV) and Photoluminescence (PL) studies. The optical properties of the ZnS nanoparticles are also discussed.
