摘要
在乙醇体系中,以氯化铕与1,2-邻苯二氧基二乙酸和二苯甲酰甲烷反应合成了三元配合物Eu-BDDA-DBM以及弱荧光离子La3+,Y3+,Yb3+和Nd3+掺杂的铕配合物.通过红外、紫外-可见、热重、荧光光谱对配合物进行了表征.红外光谱表明,单一配合物和掺杂配合物具有相似的配位结构.荧光光谱表明,La3+和Nd3+离子掺杂可以大幅度提高的铕配合物的荧光强度,其中La3+掺杂荧光强度增强最明显.
A new ternary rare earth complex Eu-BDDA-DBM and the one with 1/2 Eu^3＋ ions and 1/2 L ions （L----La^3＋, y^3＋, yb^3＋ and Nd^3＋ ）were synthesized in the alcohol solution using the reaction of rare earth chloride 1, 2-phenylenedioxydiacetic acid and dibenzoylmethane as raw materials. The complexes were characterized by IR spectra, UV spectra, TG analysis, fluorescence excitation, and emission spectra. The IR spectra indicate that the white complex has a similar coordination structure with the doped complex. The fluorescence spectra show that the fluorescence intensity of complexes of europium is increased after doped by La^3＋ and Nd^3＋ , and among them the La^3＋ containing complex has the strongest fluorescence intensity.
