Light extraction for a doubly resonant cavity organic LED: the RC2LED

摘要

The RC2LED is a substrate emitting OLED which has three additional interference layers between the ITO electrode and the glass substrate. This creates two resonant optical cavities The RC2LED has 2 resonant optical cavities. The first cavity is also present in regular1 devices and is formed by metal/organic layers/ITO. The second cavity is formed by 3 additional layers: a high refractive index layer (Nb2Os), a low refractive index layer (SiOo) and a high refractive index layer (NT^Os).
