Based on the concept, we discussed the formation process of exciplex in organic electroluminescent (OEL) device with rareearth complex and considered that exciplex is also formed in the mixinglayer and it′s formation is the result from the interaction of singlet state of ligand and the holetransport material. Therefore, exciplex emission and the central ions emission of rareearth complex is an energy competition process. Therefore, it was resonable to understand that elimination of exciplex emission means enhance of the central ion emission of the rareearth complex through adjusting molar ratio of the two molecules.展开更多
