| 摘 要： | 【目的】研究如何提高溴基钙钛矿(CH3NH3PbBr3)发光二极管的发光亮度。【方法】通过在氧化铟锡(ITO)玻璃基底上引入无机p型NiO缓冲层与有机聚合物聚(3,4-亚乙二氧基噻吩)-聚(苯乙烯磺酸)(PEDOT∶PSS)形成有机/无机杂化空穴传输层,提高空穴注入效率,降低电子溢出。【结果】引入无机p型NiO缓冲层形成有机/无机杂化空穴传输层后,发光二极管的发光亮度提高了约1倍。【结论】该方法不仅可降低PEDOT∶PSS对ITO基底的腐蚀,还能显著提高空穴注入效率,提高发光二极管的发光亮度。

| Abstract: | Objective]How to improve the brightness of bromine-based perovskite (CH3 NH3 PbBr3 )light-emitting diodes (LEDs)has drawn increasingly extensive attention.Methods]A specially designed organic/inorganic hybrid layer composed of p-NiO and PEDOT:PSS on indium tin oxide (ITO)substrate is used as hole transport layer (HTL)to improve the hole inj ection efficiency as well as to reduce the current overflow effect.Results]By utilizing the p-NiO/PEDOT: PSS hybrid HTL,the emission intensity of the CH3 NH3 PbBr3-based LED has been improved nearly one fold.Conclusion]This method can be an effective route to improve the brightness and efficiency for the perovskite LEDs due to the improved hole injection efficiency by using the p-NiO/PEDOT:PSS hybrid HTL. |
