Abstract: The ZnS nanoparticles were synthesized by solid state reaction method. The synthesized sample was characterized by powder XRD, SEM, EDAX, UV-visible, fluorescence and FT Raman analysis. The powder XRD analysis shows the broad (111), (220) and (311) peaks which confirms the formation of cubic structure. The SEM image shows the agglomerated spherical shape of morphology. The EDAX analysis shows the composition of Zn and S are 46.47% and 53.53% respectively. The UV-Visible spectrum analysis shows the absorption wavelength as 325 nm and calculated band gap 3.81 eV. The fluorescence study reveals the near band edge emission at 363 nm and defect level peaks were observed in the higher wavelength of the photoluminescence spectrum. FT Raman analysis shows the vibration frequency at 234 cm-1 is due to the longitudinal optical (LO) mode of Zn-S lattice.
