Limited outcoupling efficiencies are still a big problem in organic light‐emitting devices (OLEDs). In this contribution, a simple and general approach for enhancing the outcoupling efficiency of OLEDs is presented: by using a three‐step process, including electrospray deposition of a sacrificial material (step i), thin metal‐layer deposition (step ii), and elution of the sacrificial material (step iii), scattering metal structures are fabricated that can be used in cavity OLEDs. The integration into green‐emitting vacuum‐processed OLEDs yields in an increased luminous efficiency and external quantum efficiency (EQE) by 30% and 27%, respectively.

通过集成散射电极增强有机发光器件中的光输出耦合

在有机发光器件（OLED）中，有限的输出耦合效率仍然是一个大问题。在此贡献中，提出了一种用于提高OLED的外耦合效率的简单且通用的方法：通过三步过程，包括牺牲材料的电喷雾沉积（步骤i），薄金属层沉积（步骤ii）和牺牲材料的洗脱（步骤iii），制造可用于腔体OLED的散射金属结构。集成到绿色发射真空处理的OLED中，发光效率和外部量子效率（EQE）分别提高了30％和27％。
