摘要：

Solution-processed Cu doped nickel oxide(Cu-NiO_x) is used as a hole injection layer (HIL) inphosphorescent green organic light-emitting diodes(OLEDs). Hole injection materials are very important for achieving high performance OLEDs. Herein, solution-processed Cu doped NiO_x prepared using acombustion method is demonstrated as the HIL in OLEDs. Nickel oxide (NiO_x) thin films incorporated with p-type Cu dopants resulted in a significantly improved conductivity and hole-injection capability.The UV-ozone treated NiO_x shows significantly better hole injection than that without being treated by UV-ozone. Our results show that phosphorescent green OLEDs with UV-ozone treated Cu:NiO_x show amaximum current efficiency of 85.3 cd A^-1, which is remarkably higher than the conventional devicebased on poly(3,4-ethylenedioxythiophene): poly(styrene-sulfonate) (PEDOT:PSS) which has a maximum current efficiency of 68.3 cd A^-1.
