摘要： 许多稀土芳香羧酸配合物由于具有优良的发光性能而被用作发光材料[1, 2]和化学、生物大分子体系的探针[3]. 但对稀土芳香二羧酸配合物的发光性能的研究很少[4～6], 仅有对于邻苯二甲酸为配体的相关讨论[6, 7]. 本文以钆的苯二甲酸二元配合物作为型化合物, 测定它们的低温磷光光谱. 确定了苯二甲酸配体的最低三重态能级, 并研究了其与三价稀土离子共振发射能级的能级匹配, 发现与铽的能级匹配很好. 在此基础上, 相应地合成了铽的同多核和异多核配合物, 研究了惰性稀土离子(La3+、Gd3+、Y3+)对铽配合物发光性能的影响。

Abstract: The lowest triplet state energies of phthalic acids were determined by measuring the luminescence spectra of their corresponding gadolinium complexes as model compounds. According to the energy match principle, then a series of terbium homopolynuclear and heteropolynuclear complexes with phthalic acids were synthesized and characterized. The luminescence properties of terbium complexes and the influences of inert rare earth ions(La3+, Gd3+, Y3+)on the luminescence properties of these complexes have been studied.

Key words: europium, terbium, lanthanum, gadolinium, yttrium, phthalic acid, complex, synthesis, luminescence property
