Highly efficient blue crystalline organic light‐emitting diodes enabled by a hot exciton sensitizer PyPO

FlexMat, EarlyView.
Two different sensitization structures (hot exciton sensitizer type and exciton nanoaggregate type) were integrated into crystalline host matrix. The resulting crystalline organic light‐emitting diodes exhibit low Joule heat loss ratio and high photon output.

Printable and Stable Microlens‐Type Perovskite Quantum Dot Color‐Converting Resin Through Rheology Control for Efficient and Reliable Micropatterning for Full‐Color Displays

Small, EarlyView.
A thixotropic perovskite quantum dot color‐converting resin (thixo‐PQD resin) is developed by rheological control and robust matrix encapsulation, enabling uniform micro‐dispensing of microlens (ML) thixo‐PQD array. The resulting ML thixo‐PQD array shows improved color‐conversion relative to flat PQD films and achieves long‐term environmental stability.
