Pure and Cu-doped ZnS nanomaterials were successfully synthesized at room temperature by the chemical co-precipitation method. X-ray diffraction (XRD) pattern shows that the synthesized nanomaterials have a cubic blended structure, and the size of crystallites is around 2-3 nm. These results were confirmed by transmission electron microscopy (TEM), which matched well with the XRD results. Scanning electron microscopy and TEM micrographs of ZnS nanomaterials were in spherical shaped nature. The chemical composition is found in pure and doped ZnS nanomaterials using EDAX spectra. UV-Vis spectra show the absorption peak between 310 and 320 nm. Photoluminescence studies reveal sharp emission peaks at 439, 450 and 466nm with decreasing intensity for pure and doped nanomaterials.
