摘要 高品质铕Eu^3+红色荧光配合物是研究近紫外白光LED灯的重要发光材料,归纳铕Eu^3+红色荧光配合物的设计和合成方法,对发展我国绿色环保灯具事业具有重要的现实意义。以近年来红色荧光铕配合物研究报道为基础,对稀土Eu^3+红色荧光发光机理,稀土Eu^3+红色荧光配合物的配体设计及合成方法进行归纳和总结。制备发光稳定、强度高的铕红色荧光配合物要进行多元配体的设计,通常选择两种有离域大π键且能量与铕离子匹配的有机分子作为配体。目前已发展了很多的铕红色荧光配合物合成方法,其中液相合成是较为常规的合成方法之一。未来利用高聚物掺杂体系及纳米制备技术有望制备到更优良的铕Eu^3+的红色荧光配合物。 High-quality europium Eu^3+ red fluorescent complexes are important luminescent materials for near-ultraviolet white LED lamps.Summarizing the design and synthesis methods of Eu^3+ red fluorescent complexes has important practical significance for the development of green lamps and lanterns in China.Based on the recent reports on the red fluorescent europium complexes,the mechanism of red fluorescence luminescence of rare earth Eu^3+ and the ligand design and synthesis methods of rare earth Eu^3+ red fluorescent complexes were summarized.The preparation of europium red fluorescent complexes with stable luminescence and high intensity requires the design of multiple ligands.Two kinds of organic molecules with large delocalized bonds and energy matching with europium ions are usually selected as ligands.At present,many synthesis methods of europium red fluorescent complexes have been developed,among which liquid phase synthesis is one of the more conventional synthesis methods.In the future,it is hopeful that better red fluorescent complexes of Eu^3+can be prepared by using polymer doping system and nano-preparation technology.
