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 of the composition Tb1-x Gdx A3 (A = anthranilic acid, x = 0-1.0) were synthesized. The structure and fluorescence properties of the complex have been studied by infrared spectroscopy and fluorescence spectroscopy. The results of IR spectroscopy showed that the structure of the doping complex was similar to that of undoped terbium anthranilate. The results of fluorescence spectroscopy showed that Gd3 + sensitized the luminescence of Tb3 +, and the mechanism of fluorescence sensitization was also discussed.
