Spectra Analysis and Fluorescence Sensitization of Solid Complexes Tb_(1-x)Gd_xA_3(A=o-Aminobenzoic Acid,x=0-1)

合成了一系列组成为 Tb1-x Gdx A3 (A=邻氨基苯甲酸 ,x=0— 1.0 )的固体配合物。利用红外光谱和荧光光谱研究了配合物的结构和荧光性质。红外光谱的结果表明 ,掺杂配合物的结构与未掺杂的邻氨基苯甲酸铽相似。荧光光谱的结果显示 ,Gd3 +对 Tb3 +的发光有明显的增敏作用 ,并对荧光增敏的机理进行了探讨。

A series of solid complexes Tb 1- x Gd x A 3(A= o aminobenzoic acid, x= 0-1.0) were synthesized.The structure characteristics were investigated by FTIR spectrometry and the results indicated that the doped complexes structure were similar to that of the complex of terbium with o aminobenzoic acid.The fluorescence properties of them were investigated by using luminescence spectrometry.The results showed that the fluorescence of Tb 3+ is enhanced after doping with Gd 3+ .And the mechanism of sensitizing effect was discussed.
