| 中文摘要: |
| 作为透明导电薄膜材料，石墨烯（Graphene）因具有十分优异的力学、光学和电学特性，在未来的柔性光电器件如触摸屏、有机发光二极管（OLED）和有机光伏电池（OPV）中表现出极大的发展潜力和广阔的应用前景。然而，受面电阻大、功函数不匹配以及表面粗糙度等关键因素的影响，基于本征石墨烯薄膜的光电器件的性能较低、稳定性较差，严重阻碍了石墨烯薄膜在柔性光电器件中的发展和应用。主要针对近年来石墨烯透明导电薄膜在OLED中应用的研究进展进行概述，并总结得出可以通过石墨烯薄膜掺杂、表面功函数修饰、清洁无损转移，以及器件结构优化等方法，进一步提高器件的性能。最后分析了石墨烯透明导电薄膜在OLED器件应用中的关键技术瓶颈，并对石墨烯透明导电薄膜在OLED中的应用前景进行了展望。 |
| 英文摘要: |
| As the transparent conductive film, graphene shows great development potential and broad application prospects in future flexible electronic and optoelectronic devices, such as touch screen, organic light-emitting diodes (OLEDs), and organic photovoltaic (OPV) cells, due to excellent mechanical, optical and electrical properties. However, due to the influence of large sheet resistance (Rs), work function (WF) mismatch, surface roughness, the performance and stability of optoelectronic devices based on intrinsic graphene films are very poor, which seriously hinders the development and application of graphene in flexible optoelectronic devices. The recent research progress on the application of graphene films as transparent conductive electrodes (TCEs) in OLEDs is reviewed. Methods were also concluded including graphene doping, and surface WF modification, and clean and non-destructive transfer as well as optimization of the device structure in order to further improve the device performance. At last, the technical bottlenecks of graphene films as TCEs in OLEDs were analyzed, and the future of this field is prospected. |
