Abstract
An organic light emitting diode consisting of multiple organic layers, disposed between a transparent conducting anode and metallic cathode. The anode is provided with a metal fluoride layer to enhance the overall performance of the device, including higher power efficiency, lower voltage threshold and improved device operation stability.
Claims24
An organic electroluminescent device comprising an anode, a cathode, and an organic light emitting layer sandwiched between the anode and the cathode, the anode comprising:
- (a) a conducting anode layer, and
- (b) a metal fluoride compound layer, wherein the metal fluoride compound layer is formed by exposing the conducting anode layer to a fluorine-containing gaseous plasma in a low vacuum.
