摘要： 采用水相离子交换法合成出双掺Ce(Ⅲ)、Tb(Ⅲ)沸石材料,讨论了光谱特征和浓度猝灭。在沸石基质中观察到稀土离子间的能量传递,通过荧光光谱和荧光寿命等实验技术,系统地研究了能量传递过程,其传递机理主要是无辐射多极子近场力作用。

关键词: Ce(Ⅲ), Tb(Ⅲ), 沸石, 发光, 能量传递

Abstract: Ce(Ⅲ)-Tb(Ⅲ) exchanged zeolites have been synthesized by aqueous solution ion exchange procedures.The spectral behaviour and concentration quenching of Ce(Ⅲ) and Tb(Ⅲ) luminescence are discussed.The energy transter between trivalent rare-earth ions in ze olite host has been originally observed.The energy transfer process is systematically investi gated by luminescence spectra and luminescence lifetime experiments The mechanism of energy transfer is proposed based on the radiationless electric multipole-multipole interaction in this system.

Key words: Ce(Ⅲ), Tb(Ⅲ), Zeolite, Luminescence, Energy transfer
