Opis

Synthesis and characterization of nano-sized particles has currently been a topic of intense investigation. In recent years, much effort has been devoted to the research of doped nanostructured materials. This kind of nanomaterials exhibits unusual physical and chemical properties in comparison with their bulk counterpart. As an important II-VI material, ZnS is chemically more stable and technologically better than other chalcogenides. In this thesis, we report an effective doping process by chemical route method to obtain nanosized ZnS:Cu particles. I have prepare five different samples with different concentration of copper. I have taken pure Zinc sulphide nanoparticle and after that I have put the copper in percentage of 0.005%, 0.01%, 0.015% and 0.02%. The influence of Cu doping concentration on electroluminescence has been studied.
