摘　　要：综述了近十余年来的一些β-双酮类、苯并咪唑类、苯甲酸类、吡啶类、大环类配体与三价铕(Eu3+)和铽(Tb3+)形成的配合物在液相体系中的荧光性能。其中,重点关注了衡量配合物的荧光性能的最重要的两个标准即量子产率和荧光寿命。文中也总结了在设计和合成优良配体时应该遵循的一些原则:如配体与稀土离子能级要匹配、将溶剂分子排斥出稀土离子配位,最大程度地消除光猝灭因素和无辐射去活化作用而改善光物理性能等,以期得到高的量子产率和长的荧光寿命的稀土配合物。Abstract： The luminescent properties of trivalent europium （ Eu^3＋ ） and terbium （ Tb^3＋ ） complexes with different ligands, such as β-diketones, benzimidazoles, benzoic acids, pyridines and maerocycles in solution in the past decade were reviewed. Especially, we focus on the quantum yields and fluorescence lifetimes which are the two most important criteria to bal- ance the fluorescence properties of complexes. Some of the principles that should be followed in the design and synthesis of excellent ligands, such as the energy level of ligands should match that of the rare earth ions and it is essential to exclude solvent molecules from coordination sphere of the rare-earth ions, to eliminate factors of luminescence quenching to improve the photophysical properties.
