Summary:In this work influence of capping and doping on the optical properties of the ZnS nanoparticles is studied. The Tinospora cordifolia was used as a capping agent and silver as a dopant for ZnS. The structural studies were carried out for phase identification and optical studies such as absorption and photoluminescence to check the influence of capping and doping. The shift in absorption edge and reduced photoluminescence intensity for these samples confirmed the interaction of capping and doping agents with the ZnS matrix. The presence of impurity phase-related to modified silver confirmed the presence of silver. These samples were further used for photocatalytic studies but observed low degradation efficiency due to poor interaction between the modified ZnS surface and dye molecules.
