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.

Chiral perovskites for next‐generation chiral optoelectronics and spintronics

FlexMat, EarlyView.
Benefiting from structural inversion symmetry breaking and strong spin‐orbit coupling, chiral perovskites possess intriguing chiral optical and spin properties. We overview their advances and core applications in perovskite solar cells, circularly polarized light detectors and spin circularly polarized‐light‐emitting diodes, offering great potential ...
