DescriptionOne-dimensional (1D) ZnO nanostructures such as nanowires, nanobelts, and nanoneedles are promising semiconductor structures in nano-optoelectronic devices. The controlled growth of 1D ZnO nanostructures on a metallic substrate with good alignment, adhesion, and electrical conductivity is crucial to various applications of the materials. This project aims to develop a simple and economical approach for the synthesis of 1D ZnO nanostructures such as nanowires, nanobelts, nanocombs, nanosheets, nanoneedles and nanopencils on metallic brass (Cu-Zn) by conducting thermal oxidation under different partial pressure of oxygen. The properties of the ZnO nanostructures such as optical absorption, photoluminescence, Raman scattering, field emission, and so on will be determined, and the applicability of the materials in sensors, vacuum electronic sources, photoluminescence, and electroluminescence will be evaluated. The research work is based on the investigators’ proven methodologies and preliminary work.
