Bright organic/inorganic hybrid perov-skite light-emitting diodes (PrLEDs) are realized by using CH3 NH3 PbBr3 as an emitting layer and self-organized buffer hole-injection layer (Buf-HIL). The PrLEDs show high luminance, current efficiency, and EQE of 417 cd m(-2) , 0.577 cd A(-1) , and 0.125%, respectively. Buf-HIL can facilitate hole injection into CH3 NH3 PbBr3 as well as block exciton quenching.
采用 CH3 NH3 PbBr3 作为发光层和自组织缓冲空穴注入层（Buf-HIL），实现了明亮的有机/无机混合钙钛矿发光二极管（PrLEDs）。PrLEDs 表现出高光亮度、电流效率和外量子效率，分别为 417 cd/m(-2)、0.577 cd/A(-1)和 0.125%。Buf-HIL 可以促进空穴注入到 CH3 NH3 PbBr3 中，并阻止激子猝灭。
