Cavity-Compatible Light Extraction in Top-Emitting Microcavity OLEDs via a Gentle Internal Corrugation Layer and Resonance-Matched Narrowband Emission. [PDF]

open access: yesAdv Sci (Weinh)
A gentle internal corrugation layer conformally reshapes the microcavity OLED stack, redistributing confined optical power toward extractable channels while preserving cavity‐controlled emission. Combined with optical clear resin and a resonance‐matched narrowband pTSF emissive system, this cavity‐compatible architecture delivers an external quantum ...
