稀土(Eu,Tb)邻苯二甲酸配合物的共发光现象

Common Luminescent Phenomenon of Eu-Tb-o-Phthalate Coordination Compounds

合成了不同物质的量比的铕、铽邻苯二甲酸配合物，测试了这些配合物的发光性能．实验结果表明，配合物中铽对铕的发光有明显增强作用。

 The mixed rare earth coordination compounds of the ophthalate in the different molar proportion of Eu^+3 to Tb^+3 have been synthesized and the relation between their compositions and the luminescent character has been studied.The results show that the luminescence intensity of Eu^+3 can be enhanced obviously when Tb^+3 was added,but the luminescence of Eu^3+ to Tb^3+ ion has the quenching action.
