摘　　要：It is generally believed that exciplex is formed at the interface between a acceptor and a donor, it is not a new species, and it has a transit excited state. Based on the concept, we discussed the formation process of exciplex in organic electroluminescent (OEL) device with rareearth complex and considered that exciplex is also formed in the mixinglayer and it′s formation is the result from the interaction of singlet state of ligand and the holetransport material. Therefore, exciplex emission and the central ions emission of rareearth 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 rareearth complex through adjusting molar ratio of the two molecules.It is generally believed that exciplex is formed at the interface between a acceptor and a donor, it is not a new species, and it has a transit excited state.
