: Nanoparticles of Ce3+doped Zinc Sulphide have been synthesized using less concentration (0.01M and 0.03M) of dopant and Thiourea as capping agent by simple coprecipitation method at room temperature. The synthesized samples were analysed through PXRD, SEM, TEM, UV-visible and Photoluminescence studies. The size of particles calculated from XRD data are exactly matched with TEM results. The morphology of nanoparticles as observed by SEM and TEM images is almost spherical in shape. UV-visible absorption studies of prepared samples reveal that on Ce3+doping band gap energy of samples slightly decreased. The different functional groups present in the samples were identified by FTIR spectra. Photoluminescence emission spectra of Ce3+ doped ZnS nanoparticles exhibit broad emission with peaks in visible region.
