Single-crystalline ZnO nanorods have been synthesized by a simple solvothermal process at low temperature. Transmission electron microscopy(TEM)observations have confirmed that the as-synthesized products have rod-like morphologies with diameters ranging from several nanometers to 30 nm and lengths from 100 nm to 2μm.Such hexagonal ZnO nanorods are structurally uniform and the growth direction is identified to be [0001].Growth mechanism of the ZnO nanorods was proposed.
