| Abstract: | 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. |
