摘要

通过共蒸镀掺杂的方法

分别用氧化石墨烯和NPB掺杂作为空穴传输层以及氧化石墨烯和Alq

掺杂作为电子传输层和发光层

制备了两种不同的有机电致发光器件。器件性能测试结果表明:相对于未掺杂的参比器件

氧化石墨烯与NPB共蒸镀掺杂的器件性能降低

与Alq

共蒸镀掺杂的器件性能提高。其中

氧化石墨烯掺杂量为Alq

的10%时

器件发光亮度为掺杂前的1.2倍

电流效率为掺杂前的2倍。这一工作为进一步提高OLED性能提供了新的途径。

Abstract

Graphene oxide was explored as doping material that doped into hole transporting layer (NPB) and electron transporting layer (Alq

) via thermal co-evaporation respectively to fabricate two types of OLED devices. The experimental results indicated that thermal co-evaporation of graphene oxide with Alq

act as electron transporting layer can improve the device performance while with NPB as hole transporting layer decrease the performance. And it turns out that device doped 10% graphene oxide in Alq

layer exhibited 1.2 fold higher of luminance and 2 fold higher of current efficiency than that of updoped one.
