Abstract

In this study, highly crystallized ZnO nanorods produced with hexagonal prism-like, tower-like and tip-like ends were successfully synthesized from the starting raw material of Zn₃N₂ powder. The experimental results indicate that the different morphologies of the ends of nanorods depend on the concentration of NH₃ in the hydrothermal process. Furthermore, the size of the nanorods is significantly influenced by the synthesis temperature. Nanorods of a small diameter (about 10 nm), for example, can be produced at low temperatures. A possible growth mechanism is proposed for the formation of nanorods that exhibit different end morphologies.
