摘要：

This study examined the effects of a He/O-2 and He/SF6 atmospheric pressure plasma surface treatment of indium tin oxide (ITO) glass on the ITO surface and electrical characteristics of organic light emitting diodes (OLEDs). The OLEDs composed of ITO glass/2-TNATA/NPD/Alq(3)/LiF/Al showed better electrical characteristics, such as lower turn-on voltage, higher power efficiency, etc.. after the He/O-2 or He/SF6 Plasma treatment. The He/SF6 treatment resulted in superior electrical characteristics compared with the He/O-2 treatment. The electrical improvement as a result of the He/SF6 and He/O-2 plasma treatments is related to the decrease in the carbon and Sn4+ concentration on the ITO surface and fluorine doping of the ITO possibly indicating a change in the work function as a result of the treatments.
