Abstract

We demonstrate an effective approach to realize excitation and outcoupling of the SPP modes associated with both cathode/organic and anode/organic interfaces in OLEDs by integrating dual-periodic corrugation. The dual-periodic corrugation consists of two set gratings with different periods. The light trapped in the SPP modes associated with both top and bottom electrode/organic interfaces are efficiently extracted from the OLEDs by adjusting appropriate periods of two set corrugations, and a 29% enhancement in the current efficiency has been obtained.

摘要

我们展示了一种通过集成双周期波纹来实现与OLED中阴极/有机和阳极/有机界面相关的表面等离激元极化激元（SPP）模式的激发和外耦合的有效方法。双周期波纹由两组不同周期的光栅组成。通过调整两组波纹的适当周期，捕获在与顶部和底部电极/有机界面相关的SPP模式中的光能够有效地从OLED中提取出来，并且电流效率提高了29%。
