摘要: 77K下测得的激光激发光谱和发光光谱表明,配合物Eu(DMBM)(TPPO)2(NO3)2(DMBM:二对甲氧基苯甲酰甲烷;TPPO:三苯基氧化膦)中的Eu(Ⅲ)离子具有两种晶格格位。5D07F1(0~2)跃迁光谱说明这两种铕(Ⅲ)格位的点群对称性分别是C2v和C1(或C2或Cs)。有较高对称性(C2v)的格位在配合物中占优势。

Abstract: The two Eu(Ⅲ) sites of the Eu(DMBM)(TPPO)2(NO3)2(DMBM:dimethoxybenzoylmethanate;TPPO;triphenyl phosphine oxide) have been probed high-resolution excltation and emission spectra at 77K on the powdered polycrystaline samples. Detailed study of 5D1-7F1(J=0~2) transitions. indicates the two sites with. C2v and C1,C2 or C symmetry respectively.The'Eu(Ⅲ) site with C2v predominates in the complex.

Key words: luminescent probe, coordination compound, Eu(Ⅲ) site
