Non-degenerate wide bandgap semiconductors as injection layers and/or contact electrodes for organic electroluminescent devices |
摘要 |
An organic light emitting device is provided having a substrate (60), an anode contact electrode (64), a cathode contact electrode (61), and an organic region (62, 63) in which electroluminescence takes place if a voltage is applied between the anode (64) and cathode (61). At least one of the electrodes (61, 64) comprises a non-degenerate wide bandgap semiconductor.
