GO:PEDOT:PSS for High-Performance Green Phosphorescent Organic Light-Emitting Diode

A high-performance green phosphorescent organic light-emitting diode (GPhOLED) based on easily available graphene oxide (GO)-doped poly(styrenesulfonate)-doped poly(3,4-ethylenedioxythiophene) (PEDOT:PSS) as anode buffer layer and simple device fabricating process has been demonstrated. The GO:PEDOT:PSS-based GPhOLEDs show a better performance compared to the PEDOT:PSS only GPhOLEDs with current and power efficiencies of 52 and 41 cd/A and 36 and 27 lm/W at 1000 cd/m

, respectively. These findings shed new light on the development of high-performance GPhOLEDs.
