Abstract

In this work, ZnO microrod arrays were successfully synthesized on a curved sphere surface through thermal evaporation of a mixture of ZnS and Zn powders and using Zn foil as the substrate. Results indicated the as-grown ZnO microrod has a smooth top with an average diameter of 500 nm and a length of 1 μm. The formation mechanism of such ZnO structure is investigated through comparative experiments with varied gas flow ratios and the types of the source material. Photoluminescence of ZnO microrod exhibited a near band edge emission peak at 387nm, as well as a weak and wide peak at 509 nm induced by defect states. ZnO microrod arrays presented here have potential applications in lasers and transducers.
