摘　　要：利用简单的溶剂热法,在具有不同镓浓度的锌前驱体溶液中得到了Ga掺杂ZnO纳米粉体.采用X射线光电子能谱仪(XPS)、X-射线衍射仪(XRD)、透射电镜(TEM)、荧光光谱仪(PL)及霍尔效应测试(HES)等研究手段分别对样品的成分、形貌及光、电性能进行了研究.分析了前驱体溶液中镓浓度对产物光、电学性能的影响.Ga-doped ZnO nanopowders were obtained from zinc precursor solutions with different Ga concentrations via a simple solvo-thermal route.The optical and electrical properties of the obtained nanopowders have been investigated by XRD,TEM,XPS,PL and Hall effect measurement system（HES）.The influence of Ga concentration in zinc precursor solutions on the optical and electrical properties of the product was investigated.
