| 摘 要： | Large-scale ZnO nanowire arrays are synthesized by electrodeposition with subsequent heat treatment in atmosphere ambient at 450-650℃. Photoluminescence （PL） is investigated at 295K. Abnormal PL properties of an unusual sharp emission at 485 nm and a broad ultraviolet emission which are different from the other works of ZnO PL before are observed. Field emission scanning electronic microscopy and transmission electron microscopy results show that the length of Zn 0 nanowires is nearly 5μm and their diameter is about 70 nm. X-ray diffraction and electron diffraction results reveal that the ZnO nanowires are a polycrystalline structure.
