| 摘 要： | 本文研究了高压下无机微孔材料的相转变，并讨论了压力对离子交换的Eu（Ⅲ）NaA和Eu（Ⅲ）NaY两种以沸石分子筛为基质的稀土发光材料发光性质的影响。实验结果表明，对于不同基质材料，压力对Eu（Ⅲ）离子的光谱结构的影响，尤其是对5D0→7F1磁偶极跃迁与5D0→7F2电偶极跃迁强度比（Im/Ie）的影响十分显著。对于Eu（Ⅲ）NaA样品来说，Im/Ie值随压力的增加而增加，而对于Eu（Ⅲ）NaY样品，Im/Ie值随压力的增加而减少。

| Abstract: | The phase transitions of aluminosilicated microporous materials under high pressure have been investigated. The influence of pressure on the luminescence of exchanged Eu(Ⅲ)NaA and Eu(Ⅲ)NaY is discussed. Experiment shows that pressure has a notable influence on the Eu(Ⅲ) ions spectral structures. For the sample of exchanged Eu(Ⅲ)NaY, the value of Im/Ie decreases with increasing of pressure, and for the exchanged Eu(Ⅲ)NaA, the value of Im/Ie increases with increasing of pressure. This difference is due to the different base materials. |
