Abstract

A study was conducted to demonstrate the synthesis of ZnS nanowires homogeneously doped with gallium (Ga) and sheathed with a few layers of carbon. The study demonstrated that these nanowires are also used as precursors, to prepare nanotubes composed of ZnO and ZnGa2O4 hetero-nanostructures. It was also demonstrated that ZnGa2O 4 is an essential transparent conducting oxide with a bandgap of ca 4.5 eV. The material was found to be extensively used in field-emission displays, as a coating layer in multi-color emitters. It was found that ZnGa2O4 exhibits strong acid corrosion resistance properties in comparison to other phosphor oxides. The study also demonstrated that these heterostructured ZnGa2O4 nanotubes can be potentially used as phosphors under environmentally corrosive conditions.
