Both high luminance and efficiency are obtained from the OLEDs with the cathode of CsF/Mg:Ag/Ag. OLEDs with the CsF thickness of around 1 nm has the highest luminance. The device emits green light and the luminance reaches as high as 3,000 cd/m^2 at an injection current of 0.15 A/cm^2. The formation of alloys of CsF and Mg:Ag on the interface between an organic layer and the cathode results in the high efficient electron injection. The stability of OLEDs exposed in air after the deposition of CsF has been also discussed.
