OPTICAL, STRUCTURAL AND MORPHOLOGICAL STUDIES OF BEAN- LIKE ZnS NANOSTRUCTURES BY AQUEOUS CHEMICAL METHOD

The ZnS semiconducting nanoparticles were synthesized by simple chemical reaction of ZnCl2 and Na2S in aqueous solution. The main advantage of this method is the use of non toxic precursors and water is used as solvent. The as-prepared ZnS nanoparticles have average size of 12 nm. The structural, morphological, chemical composition and optical properties of the nanoparticles have been investigated by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infra Red Spectroscopy (FTIR), Ultra Violet Spectroscopy (UV) and Photoluminescence (PL).
