摘要：

A preparation process for ZnO nanorods (or nanowires) by use of electrochemical deposition in an aqueous solution of zinc nitrate and nitric acid at temperatures 75 degrees C was established. The surface morphologies of ZnO nanostructures can be adjusted with constant high internal quantum efficiency (IQE). The as-grown ZnO nanostructures exhibit a dominant and intense near-band-edge emission. The ZnO nanostructures present an IQE of similar to 28% measured by a He-Cd laser under excitation power density of similar to 22 W/cm(2) at a wavelength of 325 nm.
