摘　　要：稀土材料素有“工业维生素”或“工业味精”之美称,被广泛应用于信息、能源、交通、环境、航天航空等领域。稀土材料也是我国具有特色的战略资源。稀土材料独特的4f壳层电子结构具有丰富的能级结构和优良的光、电、磁、核等物理特性,使得稀土发光配合物可实现从紫外光到红外光的荧光发射,同时具有发光峰窄、稳定性好以及光色可调等特点,在有机电致发光器件研究领域引起了广泛关注。本文综述了基于合理的设计选择有机配体,调控稀土配合物宇称禁阻4f-4f跃迁和宇称允许5d-4f跃迁两种发光机制,并进一步总结其在有机电致发光器件中运用的研究进展,为新型高性能有机电致发光器件的设计与优化提供了新思路。Rare earth materials have been regarded as‘industrial vitamin’or‘industrial monosodium glutamate’,which were widely applied in information,energy,transportation,environment,aerospace and the other fields.Due to the unique 4f shell electronic structure,the rare earth materials demonstrate the excellent physical property of the optical,electrical,magnetic and nuclear aspects,acting as the strategic resources in China.Notably,the rare earth materials with the outstanding fluorescence emission from ultraviolet light to infrared light region play an important role among all kinds of luminescent materials.Significantly,the rare earth luminous complexes expected to become high-performance electroluminescence materials with the characteristics of narrow luminescence peak,high luminescence stability,and adjustable light color,and so on,which are attributed to the novel photoluminescence mechanism of both parity inhibited 4f-4f transition and parity allowed 5d-4f transition.Furthermore,a summary of recent advances in organic light-emitting diodes(OLEDs)of organic rare earth complexes supplies an insight for rationally designing and optimizing the high-performant OLEDs.
