中文摘要：

采用水热法制备了稀土Eu掺杂的Zn0纳米片状材料（ZnO：1％Eu），在稀土Eu掺杂浓度一定的条件下讨论了不同水热反应温度对纳米片结构的影响，得出材料最佳生长温度，并研究了该反应温度条件下掺杂材料的光学性能．实验结果表明，稀土铕以正三价价态成功地掺入到ZnO晶格中．在反应温度为155℃时，材料的结晶质量最好．该反应温度下PL谱图显示出Eu3＋的特征发射峰，分别位于579．6，587．8和614nm处，它们是V—V的跃迁，分别来源于Eu3＋的5D0-7Fo，^5D0-7F1和^5D0-^7F2跃迁．

英文摘要：

The ZnO： 1% Eu nanosheets were prepared by the hydrothermal process, and the effect of reaction temperature on the structures and properties of the samples were mainly discuss in the paper. The results showed the Eu3＋ ions were successfully doped into the crystal lattice of ZnO matrix. And the optimum temperature of 150℃ was given from the experiment. The sample under 150℃ condition has the best crystallization quality and shows the Eu3＋ emission of 5 D0→7 F0,5 D0→7 F1 and 5 D0→7 F2 originating from intra-atomie 4f-4f transition of Eu3＋ ions were located at 579.6,587.8 and 614 nm.
