Highly efficient organic/inorganic hybrid perovskite light-emitting diodes (PeLEDs) based on graphene anode are developed for the first time. Chemically inert graphene avoids quenching of excitons by diffused metal atom species from indium tin oxide. The flexible PeLEDs with graphene anode on plastic substrate show good bending stability; they provide an alternative and reliable flexible electrode for highly efficient flexible PeLEDs.
首次开发出基于石墨烯阳极的高效有机/无机杂化钙钛矿发光二极管（PeLED）。化学惰性的石墨烯避免了来自铟锡氧化物的扩散金属原子物种对激子的猝灭。在塑料衬底上具有石墨烯阳极的柔性 PeLED 具有良好的弯曲稳定性；它们为高效柔性 PeLED 提供了一种替代且可靠的柔性电极。
