▎ 摘　　要

The fabrication of a double-layered graphene/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) conductive film was reported, in which the PEDOT:PSS film was obtained by using spray-coating technique. The optical and electrical properties of the double-layered conductive films were investigated. A flexible green organic light emitting device (FOLED) based on the graphene/PEDOT:PSS conductive film showed a stable green emission during bending test. The introduction of PEDOT:PSS leads to the obvious improvement of light-emitting efficiency for the FOLEDs. The double-layered film can find potential application in large-area flexible optoelectronic devices. (C) 2013 Elsevier Ltd. All rights reserved.
