摘要
合成了一系列组成为Tb1 -xLaxA3(A =邻氨基苯甲酸根 ,x =0～ 0 .9)的固体配合物。利用红外光谱、X射线衍射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。X射线衍射的结果表明 ,掺杂配合物的晶体结构发生了改变。荧光光谱的结果显示 ,La3+对Tb3+的发光有显著的增敏作用。对荧光增敏的机理进行了探讨 。
A series of solid complexes Tb 1- x La x A 3 (A=o aminobenzoic acid, x =0～0.9)were synthesized. The structure characteristic of them was investigated by FTIR spectroscopy and XRD. The results indicate that the doped complexe structures are similar to that of the complex of terbium with o aminobenzoic acid, but the crystal structures are different from the complex of terbium with o aminobenzoic acid. The fluorescence properties of them were investigated by luminescence spectroscopy. The results show that the fluorescence of Tb 3+ is enhanced by doping with La 3+ . And the mechanism of sensitizing effect was discussed, which explained the phenomena very well.
