摘要:
以NaOH，Y(NO3)3·6H2O和Eu(NO3)36H2O为前驱体，通过添加络合剂PEG-2000，采用水热法，成功地合成了Y2O3：Eu3+；纳米棒和纳米管，并采用先进的测试手段对其结构和性能进行了表征与测试。探讨了Y2O3：Eu3+；纳米棒和纳米管的生长机制，同时研究了Y2O3：Eu3+；纳米晶的光致发光性能。研究结果表明，水热温度、反应时间、NaOH的添加量和PEG-2000对产物形貌有着非常重要的影响，所制备的材料具有Eu3+的特征红光发射，并在Eu3+的掺杂量为5%(摩尔分数)时样品发光最好。
Abstract:
Highly uniform and monodisperse Y2O3：Eu3+ nanorods and nanotubes were successfully prepared in large quantities using a facile hydrothermal approach assisted by a capping reagent, PEG-2000. CheaperNaOH，Y(NO3)3·6H2O andEu(NO3)36H2O were used as the raw materials. The formation mechanism of Y2O3：Eu3+ nanorods and nanotubes were discussed. The results showed that the morphologies of  Y2O3：Eu3+  were depended on the different reaction temperatures, reaction time, the addition of NaOH and PEG2000, and the prepared material had characteristic red emission of Eu3+, while identifying 5% Eu3+doped Y2O3 had the best property of luminescence.
