摘要：

In this paper, we demonstrate a simple solution-processed route to fabricate flexible blue organic light emitting diodes (OLEDs) with graphene as its bottom electrode on flexible polyethylene terephthalate (PET) substrate. The device structure consists of Al/Zinc oxide (ZnO)/poly(9,9-dioctylfluorene) (PFO)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/Graphene/PET. The PFO as a blue emitter layer and the ZnO nanoparticles as electron transport layer were deposited by using spin-coating technique. The flexible blue OLEDs based on graphene anode exhibits a stable deep blue emission with a CIE color coordinates of (0.17, 0.17). This study suggests a simple fabrication approach to construct graphene electrode-based flexible blue organic light emitting diodes. (C) 2015 Elsevier Ltd. All rights reserved.
