Organic electroluminescent device with continuous organic medium |
摘要 |
An organic EL device includes a cathode, an organic electroluminescent layer and an anode, laminated in sequence. The organic layer is composed of a continuous organic medium AxBy, where A and B are components capable of transporting electrons and holes, respectively, x represents the content of the A component with a value ranging from 0 adjacent the anode to 100% adjacent the cathode, and y represents the content of the B component with a value ranging from 0 adjacent the cathode to 100% adjacent the anode. The lifetime of the device is improved by the elimination of heterojunctions in the continuous organic medium and suppression of the re-crystallization tendency of the organic materials. At least one fluorescent dye or pigment is incorporated in the organic layer to improve efficiency and color of the luminescence.
