ZnO shows good chemical inertness and bio-compatibility. Also, ZnO is the only material which possesses good piezoelectric and semiconductor properties. ZnO nanorods have attracted much interest due to their unique physical and chemical properties and potential for diverse electronic and photonic device applications in areas such as surface acoustic wave, photonic crystals, light-emitting diodes, photodetectors, optical modulator waveguides, varistors, gas sensors, and solar cells. In this paper, the preparation of ZnO nanorods, their formation mechanisms, and their applications in recent years are briefly summarized. At last, the promising prospects for the utilization of ZnO nanrods, especially as nano devices and nano generators are given.
