Simple, inexpensive way of fabricating high quality Zn(O)S nanoparticles by varying pH

In this work, a simple, inexpensive room temperature chemical bath deposition is proposed to synthesize high-quality Zn(O)S nanoparticles of varied composition. The band gap of these nanoparticles is found to alter by varying their chemical composition. Through this study, the formation of quantum confined ZnS and ZnOS nanoparticles as a function of pH is confirmed. A possible mechanism for the formation of these nanoparticles with respect to pH is discussed here.
