"monolayer graphene anode instead of the problematic ITO... The graphene was patterned using photolithography and its conductivity was enhanced by doping with nitric acid prior to deposition of the OLED stack. The electrical and optical performances of the as-fabricated graphene-based OLEDs were identical to the control devices with conventional ITO anodes"
