Electrically Injected Hybrid Organic/Inorganic III-Nitride White Light-Emitting Diodes Based on Rubrene/(InGaN/GaN) Multiple-Quantum-Wells P-N Junction

IEEE Photonics Journal, 2019
It is known that the commercialized white light-emitting diodes (WLEDs) depend on phosphor conversion, which is limited by the unbalanced carrier injection in multiple quantum wells (MQWs) and low down-conversion efficiency.

Stretchable Metal Halide Perovskite Color Conversion Layers with Block Copolymer Dispersant

Advanced Optical Materials
AbstractStretchable luminescent nanocomposites with metal halide perovskite (MHP) emitters are in high demand as deformable color‐conversion layers (CCLs) for vivid‐colored form‐factor free displays. However, the immiscibility of the MHP crystals with an elastomeric polymer matrix induces particle aggregation with resultant luminescence quenching ...
