Abstract
A simple two-step approach to produce highly ordered ZnO nanotube arrays is introduced. In the first step, Zn nanotubes were prepared by the electrodeposition of Zn into the pores of anodic alumina membrane (AAM), and then they were oxidized in air and converted into ZnO nanotubes. This approach is very simple, molecular anchor free, and is capable of growing ZnO nanotubes at low temperature. The ZnO nanotubes synthesized by this method exhibit an intense and sharp cathodoluminescence at 378 nm and a weak defect emission at about 500 nm at room temperature, indicating good quality of the prepared samples. Our approach is very general, which provides an alternative method for preparing highly ordered metal oxide nanotube arrays with good quality at relatively low temperatures. © 2008 Elsevier B.V.
