Zinc Sulfide (ZnS) nanoparticles of high level of photoluminescence have been successfully prepared using chemical precipitation method with Sodium HexaMeta Phosphate (SHMP) as capping agent. Particle sizes with band gap for undoped and doped nanoparticles are calculated using Ultraviolet / Visible (UV/Vis) absorbance spectra. The diameter of the particles is determined using X-ray diffraction (XRD) analysis. Transmission electron microscope (TEM) images imply that ZnS particles are evenly embedded in SHMP polymer. A good study of scanning electron microscope (SEM) images show that the particles have smooth surface passivated with polymer. Fourier transform infrared (FTIR) spectroscopy of ZnS/SHMP nanoparticles and SHMP shows strong chemical bond between ZnS nanoparticles and host SHMP polymer. An emission peak of the undoped and doped ZnS nanoparticles is recorded by Photoluminescence spectra which imply the existence of interesting optical properties.
