Paper Abstract

Graphene is an emerging transparent conductor that plays a potential role in organic optoelectronic device. Here we report the fabrication of a polymer light emitting diode employing graphene as anode by solution process. The hydrophobic graphene on PET substrate is modified through interface engineering to obtain a good poly(3,4- ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) wettability, which yields a composite electrode with low sheet resistance, high optical transmittance and high work function. The resulting device exhibits good electroluminescence emission and excellent flexibility, which is attributed to our high quality graphene and satisfying interfacial modification. Such polymer light emitting diode employing this green and smart graphene composite anode will promote the development of organic electroluminescent and photovoltaic devices toward a flexible and wearable era.
