Abstract

Higher ZnO nanorod growth rates were obtained in separate pH levels of hydrothermal solution, 10.6 and 13.0. ZnO nanorods synthesized in a solution with a pH of 10.6 exhibited improved optical properties over those synthesized in a solution with a pH of 13.0. It is suggested that fewer oxygen deficiencies, a stoichiometric ZnO structure, and less influence of structure defects are the reasons for improved optical properties for the ZnO nanorods synthesized at a pH of 10.6. From the fact that Zn(NH3)4 2+ is a main reaction species at a pH of 10.6, it is believed that the reaction path via Zn(NH3)4 2+ has an advantage in exhibiting better optical properties of ZnO nanorods.
