制备了一种双层石墨烯/聚（3,4-乙烯二氧噻吩）：聚苯乙烯磺酸盐（PEDOT:PSS）导电薄膜，其中PEDOT:PSS层采用喷涂技术制备。制备了一种基于石墨烯/PEDOT:PSS导电膜的柔性白光有机发光器件。将荧光材料三（2-苯基吡啶）铱（Ir(ppy)3）与荧光染料5,6,11,12-四苯基萘（Rubrene）共掺杂到4,4 ' -N,N ' -二咔唑-联苯（CBP）中。以N，N ' -二苯基-N，N ' -双（1-萘基）-（1,1 ' -联苯基）-4,4 ' -二胺（NPB）和4,7-二苯基-1,10-菲罗啉（Bphen）分别作为空穴传递层和电子传递层，以4,4 ' -双（2,2 ' -二苯基乙烯基）-1,1 ' -联苯（DPVBi）作为蓝光发光层。该器件呈现出纯白光发射，国际委员会De I 'Eclairage坐标为（0.31,0.33），并且在曲率半径为10 mm的弯曲循环测试中表现出优异的发光稳定性。
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.
