摘　　要：用简单的无催化剂、高温热蒸发方法制备氧化锌纳米棒 ,得到了具有良好晶体结构和规则外形的ZnO纳米棒 ,长度为 (1- 5 ) μm ,直径约几十纳米。测量了ZnO纳米棒的光致发光特性。讨论了实验条件对纳米棒生长结果的影响 。A large amount of ZnO nanorods were prepared by thermal evaporation without any catalyst.The ZnO nanorods have the lengths of 1-5 μm and diameters of about several tens of nanometers.The photoluminescence of as grown ZnO nanorods was studied.Influence of reaction temperature,time,and carrier gases etc.on the quality of the nanorods were discussed.A preliminary growth mechanism of the ZnO crystal nanorods was proposed.
