The workfunction of graphene was modified using solution‐processed molybdenum oxide (MoO x ) resulting in efficient charge injection in PLED. After the doping, the sheet resistance of five‐layer graphene with optical transmittance of ~88 % was as low as ~180 Ω sq ‐1 . Compared with the pristine graphene, maximum current efficiency was enhanced by 255 %.
