A　double-layered　graphene/poly(3,4-ethylenedioxythiophene):　poly(styrenesulfonate)　(PEDOT:PSS)　conductive　film　was　prepared,　in　which　the　PEDOT:PSS　layer　was　obtained　by　using　spray-coating　technique.　A　flexible　white　phosphorescent　organic　light-emitting　devices　based　on　the　graphene/PEDOT:PSS　conductive　film　was　fabricated.　Phosphorescent　material　tris(2-phenylpyridine)　iridium　(Ir(ppy)3)　and　the　fluorescent　dye　5,6,11,12-　tetraphenylnapthacene　(Rubrene)　were　co-doped　into　4,4′-N,N′-　dicarbazole-biphenyl　(CBP)　host.　N,N′-diphenyl-N,N′-bis(1-naphthyl)-　(1,1′-biphenyl)-4,4′-diamine　(NPB)　and　4,7-diphenyl-1,10-　phenanthroline　(Bphen)　were　used　as　hole-transporting　and　electron-transporting　layer,　respectively,　and　4,4′-bis(2,2′-diphenylvinyl)-1,1′-　biphenyl　(DPVBi)　was　used　as　blue　light-emitting　layer.　The　device　presented　pure　white　light　emission　with　a　Commission　Internationale　De　I＇Eclairage　coordinates　of　(0.31,　0.33)　and　exhibited　an　excellent　light-emitting　stability　during　the　bending　cycle　test　with　a　radius　of　curvature　of　10　mm.　©　2014　Elsevier　B.V.　All　rights　reserved.
