Abstract
In this work, we report on the synthesis of ZnS semiconductor nanoparticles stabilized with sodium hexa meta phosphate (SHMP). Capped ZnS nanoparticles were synthesized by a chemical route. The as obtained nanoparticles were characterized by X-ray diffraction (XRD), uv-vis absorption spectroscopy, and photoluminescence (PL) spectroscopy. The average particle size was found to be 2-3 nm. UV-Vis optical spectra showed a blue shift with respect to the bulk counterpart. The room temperature photoluminescence spectra of the nanoparticles showed emission peaks in the range of 363 - 446 nm at excitation wavelength of 325 nm for different concentrations of SHMP. Photocatalytic degradation of bromophenol blue dye was done using capped ZnS nanoparticles. It took about 3.5 hours to degrade the dye completely under uv irradiation.
