以氧化石墨烯(GO)为复合阳极，掺杂聚(3，4-乙二氧基噻吩基)：聚苯磺酸盐(PEDOT：PSS)，制备了无铟锡氧化物有机电致发光器件(OLED)。在最佳条件下，与纯PEDOT：PSS阳极相比，基于PEDOT：PSS/GO复合阳极的OLED效率提高了55%。PEDOT：PSS/GO复合阳极具有较低的空穴注入势垒，有助于提高器件效率。此外，与纯PEDOT：PSS薄膜类似的高透过率和良好的表面形貌也有助于提高效率。显然，复合阳极将普遍应用于需要光滑透明阳极的有机光电器件中。(C)2015爱思唯尔B.V.保留所有权利。
We have demonstrated an indium-tin-oxide free organic light-emitting device (OLED) with improved efficiency by doping poly (3,4-ethylene dioxythiophene): poly (styrene sulfonate) (PEDOT:PSS) with graphene oxide (GO) as a composite anode. In comparison with a pure PEDOT: PSS anode, 55% enhancement in efficiency has been obtained for the OLEDs based on the PEDOT: PSS/GO composite anode at an optimal condition. The PEDOT: PSS/GO composite anode shows a lower hole-injection barrier, which contributes to the improved device efficiency. Moreover, both high transmittance and good surface morphology similar to that of the pure PEDOT: PSS film also contribute to the enhanced efficiency. It is obvious that composite anode will generally be applicable in organic optoelectronic devices which require smooth and transparent anode. (C) 2015 Elsevier B.V. All rights reserved.
