摘　　要：合成了一系列异核配合物(Tb1-xErx).L3.phen.1/2H2O(x=0.000~0.200,L为2-噻吩甲酸,phen为邻菲罗啉)。对配合物进行了组成分析,摩尔电导,IR光谱及荧光激发和荧光发射光谱的测定。荧光光谱测定表明,配合物中Er3+对Tb3+的发光产生猝灭作用,随着Er3+加入量的增大荧光发射强度大大减弱。Different nuclear （Tb1-xErx） ·L3,·phen· 1/2H2O （x = 0.000 ～ 0.200, L as 2 - thiophene carboxylic acid and phen for 1.10- phenanthroline） coordination compounds were synthesized, and were studied by means of composition analysis, moler conductance, IR spectra and fluorescence excitation and emission spectra. In the fluorescence emission, intensity of Tb^3＋ was descended in the mixed complexes （Er^3＋ was mixed）, Er^3＋ has a quenching effect on the complexes of Tb^3＋ in the ratio of Tb^3＋ ：Er^3＋ = 0.999： 0.001 - 0.800：0.200.
