摘要
有机电致磷光材料可以同时利用单线态和三线态激子发光,具有发光效率高等优点,成为近年来研究的热点。本文综述了以铱为内核的有机电致磷光材料的研究进展、存在问题和研究趋势,并简要介绍了用于制作有机磷光器件的主体材料。
Phosphorescent electmluminescent materials and devices are one of prime focuses of organic lightemitting device research in recent years due to their ability to efficiently utilize both singlet and triplet excitons and having higher efficiency. Research advances, problems and developing tendency of organic phosphorescent electroluminescent materials with iridium core are reviewed, and the host materials for preparing devices are introduced briefly.
