摘要
用Ｓｏｌ－Ｇｅｌ过程制备了一系列稀土β－二酮类配合物掺杂的ＳｉＯ２凝胶，测量了这些掺杂ＳｉＯ２凝胶的光声光谱．与固体配合物相比，掺杂ＳｉＯ２凝胶的光声光谱吸收峰发生蓝移，荧光发射峰发生红移．从无辐射跃迁角度研究了掺杂凝胶的Ｅｕ－β－二酮类配合物的分子内能量传递模型．
A series of rare earth β diketone complexes doped silica gel have been prepared by Sol Gel technique. The photoacoustic and fluorescence spectra of these gel have been measured. Compared with the solid complexes, emission peaks of these doped silica gel show redshift while photoacoustic absorption peaks blueshift. The intramolecular energy transfer processes of Eu β diketones doped silica gel have been studied.
