以NaOH,Y(NO3)3·6H2O和Eu(NO3)3.6H2O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:Eu^3+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:Eu^3+纳米棒和纳米管的生长机制,同时研究了Y2O3:Eu^3+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Eu^3+的特征红光发射,并在Eu^3+的掺杂量为5%(摩尔分数)时样品发光最好。

Highly uniform and monodisperse Y2O3 : Eu^3+ nanorods and nanotubes were successfully prepared in large quantities using a facile hydrothermal approach assisted by a capping reagent, PEG-2000. Cheaper NaOH, Y( NO3 ) 3·6H2O and Eu( NO3 )3 · 6H2O were used as the raw materials. The formation mechanism of Y2O3 : Eu^3+ nanorods and nanotubes were discussed. The results showed that the morphologies of Y2O3 : Eu^3+ 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 Eu^3+ , while identifying 5% Eu^3+ -doped Y203 had the best property of luminescence.
