We have provided the Cu doped zinc sulfide (ZnS:Cu) nanoparticles using a wet chemical synthesis. In principle, the nanoparticles are provided by mixing the reactants in a double distilled water solvent. We have used the mercaptopropionic acid as the capping agent. We have obtained the physical properties of the nanoparticles using the methods: UV absorption, photoluminescence spectroscopy, and X-ray diffraction analysis. The average size of nanoparticles is obtained in the range 3-6 nm. In addition, the X-ray diffraction pattern of ZnS:Cu nanoparticles reveals a zinc-blende crystal structure at room temperature.
