摘　　要：有机磷光电致发光可以同时利用单重态和三重态的激子,理论上可使器件的内量子效率达到100%而在近几年倍受关注。文章从发光机理、基质材料、掺杂剂材料和载流子阻挡材料的特征以及发白光的磷光电致发光器件几个方面扼要阐述了该领域的研究进展。Eletroluminescences based on organic phosphorescent complexes has drawn particular attention in recent years. The advantage of phosphorescence is that they can utilize both singlet and triplet exci ton states which can reach to 100 % internal quantum efficiency theoretically. In this review, the progress of research in this field about the electrophospherescent mechanism, the characteristics of host, phosphorescent dopants and charge carrier blocking materials and the white electrophorescence device have been discussed briefly.
