摘要
合成了一系列组成为 Tb1-x Lnx A3 (L n=Gd、Y、La,A=对氨基苯甲酸 ,x=0— 0 .9)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 ,结果表明 ,掺杂配合物的结构与未掺杂的对氨基苯甲酸铽相似。荧光光谱的结果显示 ,Gd3 +对 Tb3 +的发光有明显的增敏作用 ,探讨了荧光增敏机理。
A series of solid complexes of Tb 1-x Ln xA 3(Ln=Gd,Y,La,A=p -aminobenzoic acid,x=0? ?.9 ) were synthesized and the structure chara cteristics were investigated by FTIR spectrometry,which indicates that the doped complex structure is similar to that of the complex of terbium with p-am inobenzoic acid.The fluorescence properties of the compounds shows that the fl uorescence of Tb 3+ is enhanced after doping with Ln.The mechanism of sensi tizing effect was discussed.
