摘要：

ZnO nanorods were synthesized using the sol-gel method., and the effects of annealing temperature and Ce doping on the morphologies and optical properties of ZnO nanostructures were investigated in detail. The XRD measurements showed,that the as-synthesized ZnO nanostructures had a hexagonal wurtzite structure. SEM images showed that uniform nanorods formed at 900 degrees C. Photoluminescence measurements showed an ultraviolet emission peak and a relatively broad visible light emission peak for the samples sintered at different temperatures. The UV emission peak bathochromically shifted when the annealing temperature rose from 850 to 1000 degrees C. Ce doping decreased the synthesized temperature of the ZnO nanorods to 500 degrees C, and the UV peaks hypsochromically shifted.
