摘要

在有机发光二极管(oled)中，在发光效率-电流密度特性中观察到滚降现象。虽然HAT-CN倒置OLED的发光效率是MoOx倒置OLED的1.5-2倍，但前者的最大发光效率出现在更高的电流密度下。另一方面，与传统OLED相比，倒置OLED的发光效率在达到最大值后迅速下降。人们认为，这种脱落依赖于载体注射。

Correlation between Roll-Off Phenomena and Carrier Injections for OLEDs

In organic light-emitting diodes (OLEDs), the roll-off phenomenon was observed in the EL efficiency - current density characteristics. Although the EL efficiency in the inverted OLED with HAT-CN was 1.5–2 times higher than that in the inverted OLED with MoOx, the former maximum EL efficiency was observed in the higher current density. On the other hand, the EL efficiency in the inverted OLEDs decreased rapidly after the maximum as compared with the conventional OLED. The roll-off was thought to depend on carrier injections.
