Abstract
We report on the effect of ambient gas on the OLED degradation. The operating voltage and quantum efficiency increases when the device is exposed to the atmospheric gas and then returns to the initial level of the device in vacuum when the atmospheric gas is evacuated. These changes in the OLED performance can be attributed to the ambient gas pressure.
