Abstract

Cathodes made with Al-LiF or Al-CsF composites are found to enhance the performance of organic light-emitting devices. With a composite cathode, devices based on an organic bilayer structure have shown lower operating voltage, higher efficiency and better forward light output than devices with LiF/Al, Mg or Al cathode. Unlike devices with Al and Li alloy cathode, OLEDs with composite cathode can be made with good reproducibility.
