Growth mechanism and optical property of ZnO nanocrystals synthesized by corrosion of Cu–Zn alloy

Abstract

ZnO nanostructures are usually employed to modify the electrode for sensor construction in terms of its biocompatibility and high electron mobility. A simple corrosion of Cu–Zn alloy method for the production of ZnO nanostructures, which was used as the electrode-modified material, is presented in this paper. The growth morphology of ZnO on the Cu electrode could be controlled by the sputtering power of zinc. The possible growth mechanism of ZnO nanocrystals formation by the method has been tried to discuss as well as the optical properties have been demonstrated. Given the simplicity of the procedure and without the use of any organic reagent, the method described here is likely to be of interest in biosystem applications.
