Abstract
Organic electrophosphorescent devices can be used to circumvent the limitation in quantum efficiency of organic electroluminescent devices due to the spin-forbidden of triplet exciton transition. Recent progress in organic electrophosphorescent devices and materials is reviewed. The development of host materials and guest materials is discussed, especially the host and guest materials for blue electrophosphorescent devices.
