The study of group II-VI semiconductor nanomaterials have shown widespread interest due to their potential application. Amongst this group, Zinc sulfide (ZnS), which has further improved optical or magnetic properties when doped with one or more transition metal, is versatile and promising for diverse applications such as in the field of photocatalysis, imaging and some electronic devices. In the current study silver doped ZnS nanoparticles were synthesized by varying the doping concentration of Ag from 0.05% to 10%. The Ag doped ZnS were synthesized without capping agent by chemical co-precipitation method in de-ionized water. The synthesized nanoparticles have a narrow particle size distribution with improved optical properties. The phase analysis and optical properties of the doped ZnS nanoparticles have been carried by powder X-ray diffraction, UV–vis spectrometer and photoluminescence spectrometer. The result shows doping of Ag ions in ZnS nanocrystals, and improved optical property is the result of the sulfur atom interaction with metal ions on the surface of the nanocrystals. The synthesized ZnS nanoparticles doped with silver can be a promising agent for photocatalytic activity.
