| 摘 要： | 稀土离子的敏化发光研究一直是有机稀土发光配合物领域的热点问题。在活体生物成像和荧光免疫分析领域，与紫外光激发相比，可见光激发具有可有效降低背景光的干扰和减少对生物组织的损伤等优点，因此，可见光激发有机稀土配合物的发光研究受到了稀土探针制备方面研究人员的广泛关注。在上述配合物中，三价铕离子配合物可获得较高的发光量子产率，且其特征发射为红光，因此，这类配合物在成像和免疫分析领域更加引起了研究者的极大兴趣。本文就近年来可见光敏化有机铕配合物的发光机理、敏化配体的类型、配合物的发光性能等方面进行了综述，分析了不同的敏化配体对三价铕离子配合物发光性质的影响，指出了要从如何制备敏化配体方面来探索创造具有优异发光性能的有机铕配合物。

| Abstract: | Sensitized luminescence of lanthanide ions has been a research focus in the field of organic lanthanide luminescence. Visible-light excitation has such positives as efficient interference reduction of background fluorescence and damage reduction to biological tissue in the fields of live bioimaging and fluorescent immunoassay, as compared with ultraviolet excitation. Visible-light excitated organic europium complex luminescence has been received attention in the research on the preparation of lanthanide probe. Trivalent europium complex can obtain higher luminescence quantum yield and its characterized emission light is red in the above complexes, so such complexes excite much more research interest in the applications of imaging and immunoassay. This paper reviews the luminescent mechanism, the species of sensitized ligands and luminescence properties of visible-light excitated organic europium complex in recent years. The paper also analyzes the impacts of different sensitized ligands on the properties of lanthanide ion complexes luminescence, and points out how to synthesize organic europium complexes with excellent luminescence property from the preparation of sensitized ligands |
