系列新型铕—β—二酮三元及四元混配化合物发光性质研究

本文报道了五种铕－β－二酮（二苯甲酰甲烷ＤＢＭ，噻吩甲酰三氟丙酮ＴＴＡ）－丙烯酸（ＨＡＡ）三元及四元混配化合物的紫外、荧光光谱，量子产率瞬态光谱。观察到主配体、协同配体对配合物吸收及发射光谱的影响。测得配合物溶液中铕离子＾５Ｄ１能级向＾５Ｄ０能级的传能过程及荧光寿命，发现室温下溶液中以ＴＴＡ为主配体的四元或三元配合物的寿命相近且远大于以ＤＢＭ为主配体的配合物。

Study on luminescence of the serial new ternary or tetradic complexes complexes of Eu (III) with beta-diketone]

The UV absorption, fluorescence, unstable spectra and quantum yields of five ternary or tetradic complexes of Eu (III) with beta-diketone (dibenzoyl methane, thenoyltrifluoroacetone), acrylic acid and other ligands were reported. The influences of the first and second ligands on absorption and luminescence spectra were found. The lifetimes and the processes of energy transfer of Eu3+ from 5D1 to 5D0 in complex solutions were measured. It was found that the lifetimes of Eu3+ complexes with TTA are approximate to each other and larger than those of complexes with DBM.
