摘要:

以NaOH，Y(NO₃)₃·6H₂O和Eu(NO₃)₃6H₂O為前驅體，通過添加絡合劑PEG-2000，采用水熱法，成功地合成了Y₂O₃：Eu³⁺；納米棒和納米管，并采用先進的測試手段對其結構和性能進行了表征與測試。探討了Y₂O₃：Eu³⁺；納米棒和納米管的生長機制，同時研究了Y₂O₃：Eu³⁺；納米晶的光致發(fā)光性能。研究結果表明，水熱溫度、反應時間、NaOH的添加量和PEG-2000對產物形貌有著非常重要的影響，所制備的材料具有Eu³⁺的特征紅光發(fā)射，并在Eu³⁺的摻雜量為5%(摩爾分數)時樣品發(fā)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⁺�猟oped Y₂O₃ had the best property of luminescence.
