摘  要:
以吲哚-3-乙酸为配体,合成了稀土镨和铕的配合物。利用元素分析、红外光谱(IR)、热分析(TG-DTG)、紫外光谱(UV)和荧光光谱(FS)等分析手段对配合物的组成和光学性质等进行了分析与表征,推测配合物的通式为RE(L)3.2H2O;通过对荧光光谱的研究表明,稀土镨配合物的发光性能优于稀土铕配合物,配体L与Pr3+间能级差较匹配,分子内传能效率高。

摘  要:
The lanthanide complexes of Pr and Eu based on the inodole-3-acetic-acid were synthesized in this paper.The lanthanide complexes were characterized by elemental analysis,IR spectra,thermogravimetric analysis,UV spectra and fluorescence spectra.According to elemental analysis and TG-DTG,the molecular formula was determined to be RE(L)3·2H2O.The fluorescence spectra demonstrated that Pr(L)3·2H2O had better fluorescence performance than Eu(L)3·2H2O.And this indicated that the energy level difference between the triplet state of ligand L and the emission energy of Pr3+ was well matched.
