Influence of the precursor and annealing temperature on the hydrothermal growth of ZnO nanostructures

Abstract

Wet synthesis of zinc oxide (ZnO) has been reported as an effective and low cost process for large production thin films. The purpose of this project is to investigate the effect of different precursor, different concentration and annealing temperature on the growth of ZnO nanostructures. The ZnO nanostructures is synthesised via a hydrothermal process on a glass substrate and characterized using Field Emission Scanning Electron Microscopy (FESEM). The morphological changes of the nanostructures are systematically investigated as a function of precursors and concentration as well as annealing temperature. The process use two different types of precursor which are Zinc acetate dihydrate and Zinc nitrate hexahydrate.
