In this study, we focused on the fabrication of two types of ZnO nanostructures, nanorods and nanowires, using different techniques. ZnO nanowires were fabricated by cathodically induced sol-gel electrodeposition using an anodic aluminum oxide (AAO) template. ZnO nanowires were approximately 65 nm in diameter and 10 mu m in length. Also, ZnO nanorods were fabricated by a hydrothermal technique using ZnO seed layer coated glass substrate. ZnO nanorods were approximately 30 nm in diameter and 1 mu m in length. Obtained vertical aligned ZnO nanowires and nanorods were characterized by X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) and UV-vis spectrophotometry. (C) 2011 Elsevier B.V.
