Abstract
An organic electroluminescent device includes an emitting layer comprising AxByCz inserted between the anode and the cathode. The emitting layer with different materials is a continuously mixed single layer in the organic electroluminescent device without heterojunctions. Moreover, a transporting auxiliary comprising LiF alone or a mixture comprising the hole transporting material, the electron transporting material AxBy and a % wt is inserted between the emitting layer and the cathode electrode.
