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.
Claims25
An organic electroluminescent device comprising an anode, a cathode, and a plurality of organic layers sandwiched between said anode and said cathode;
- said anode further comprising:
- (a) a conducting anode layer, and
- (b) an anode modification layer, wherein the said anode modification layer is formed by exposing the said conducting anode layer to a fluorine-containing gaseous plasma in a low vacuum.
