Abstract:
An organic electroluminescent device comprises an anode, a first organic light emitting layer, an exciton control layer, a second organic light emitting layer, and a cathode that are successively stacked, wherein the first organic light emitting layer comprises a hole transport type host material and a first doped material; the exciton control layer is provided on the surface of the first organic light emitting layer away from the anode; the exciton control layer comprises a first hole transport material and a first electron transport material; the second organic light emitting layer comprises an electron transport type host material and a second doped material; the cathode is provided on the side of the second organic light emitting layer away from the anode; and one of the first doped material and the second doped material is a fluorescence-doped material, and the other is a phosphorescence-doped material.
