摘　　要：为了得到发光性能更好的稀土荧光配合物,合成了以 BA、1,10—phen 为第1和第2配体系列铕、铽双核稀土有机配合物Eu_(1-x)Tb_x(BA)_3phen,并测试了不同浓度下各个配合物的紫外吸收光谱和荧光光谱,同时对双核稀土配合物的能量转移过程进行了讨论。结果表明,在合成的系列配合物中,配体苯甲酰丙酮和1,10-phen 是 Eu^(3+)的优良配体,第2种稀土离子 Tb^(3+)的掺入对稀土离子 Eu^(3+)的发光有明显的敏化效应。目标配合物是一种发光性能良好的稀土配合物。In order to get better luminescence performance,binuclear rare earth complex of Eu^3＋-doped ith Tb^3＋ with benzoylacetone（BA） （as the first ligand ） and 1,10-phenanathroline（1,10-phen） （ as the second ligand） were synthesized. The properties of the complex Eu1-x Tbx （BA）3phen in different concentration were characterized by UV absorption spectra and fluorescent spectra, and also the energy transfer mechanism in the complexes was discussed. The result demonstrated that BA and 1,10-phen were appropriate ligands for the Eu^3＋ , and Tb^3＋ had a strong sensitization effect on the fluorescence properties of Eu^3＋. The synthesized complex has excellent luminescent properties.
