| 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 (CH3NH3PbBr3) 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 injection 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 CH3NH3PbBr3-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. |
