稀土铕铽四元配合物的光学性能研究
Research on optical characteristic of europium and terbium quarternery complex
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Eu1-xTbx(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Eu3+的优良配体,第2种稀土离子Tb3+的掺入对稀土离子Eu3+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。
Abstract
In order to get better luminescence performance,binuclear rare earth complex of Eu3+-doped with Tb3+ 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-xTbx(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 Eu3+,and Tb3+ had a strong sensitization effect on the fluorescence properties of Eu3+.The synthesized complex has excellent luminescent properties.
