倒置有机发光二极管(Inverted organic light⁃emitting diodes,IOLEDs)因其结构容易与n型薄膜晶体管技术集成而得到了广泛研究。在IOLEDs研究中,为了使电子能从底阴极有效注入电子传输层,对各式各样的电子注入层结构进行了研究。本文制备并研究了采用超薄金属Mg作为电子注入层的高效率绿色磷光IOLEDs。研究发现超薄金属Mg薄膜具有优良的透光性;基于2 nm厚Mg电子注入层的IOLEDs具有最优的发光性能,其启亮电压、最大电流效率和外量子效率分别为3.06 V、46.5 cd/A和13.3%。
Inverted organic light-emitting diodes (IOLEDs) consist of a bottom cathode followed by the formation of an electron injection layer (EIL), an electron transport layer (ETL), a light emission layer (EML), a hole transport layer (HTL) and an anode, which have been widely investigated to match the existing n-type thin film transistor technology. In IOLEDs research, various EIL structures were studied to improve the efficiency of electron injection from the bottom cathode to ETL. In this paper, we report on high efficiency green phosphorescent IOLEDs utilizing ultra-thin Mg as EIL. The ultra-thin Mg films deposited on quartz substrates exhibited excellent light transmittance. IOLEDs based on the 2 nm Mg as EIL demonstrated the optimal device performance, with the maximum current efficiency, the maximum external quantum efficiency and turn-on voltage of 46.5 cd/A, 13.3% and 3.06 V, respectively.
