Zinc sulfide has been recognized as a promising nanomaterial which could be applied for solar collector. This work has aimed at synthesis of ZnS nanoparticles by reversed micelle of Triton X-100 and cyclohexane. Molar ratio of water to Triton X-100 and concentration of zinc and sulfide ions play an important role in controlling the size of ZnS nanoparticles. X-ray powder diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and UV-Vis spectroscopy have been used for characterization of the synthesized ZnS nanoparticles. Examination of photoluminescence of the synthesized ZnS nanoparticles reveals its size dependence.
