Blue‐hazard‐free single‐emissive‐layer white organic LEDs based on an anti‐quenching narrowband blue emitter

open access: yesFlexMat, EarlyView.
A blue‐hazard‐free single‐emissive‐layer white OLED is realized using an anti‐quenching multiple‐resonance TADF emitter, BNCT. By integrating a sterically protected MR core with efficient energy transfer capability, BNCT enables warm‐white emission with high efficiency, negligible hazardous blue photons, and a simplified device architecture for next ...

Enhanced blue emission in silica‐confined mixed‐halide perovskite quantum dots via releasing residual stress

open access: yesInfoMat, EarlyView.
Residual tensile stress is identified as a key factor responsible for the low luminous efficiency in silica‐confined blue‐emitting CsPb(Cl/Br)3 quantum dots. A hydrothermal treatment enables stress release in these quantum dots and significantly enhances their luminous efficiency.
