Balancing Ultrafast Decay and High Light Yield in PEA 2 PbBr 4 Crystals Through Strain‐Regulated Exciton Localization

ABSTRACT Ultrafast scintillators are indispensable for advanced radiation detection. Nevertheless, reconciling sub‐nanosecond temporal response with high light yield remains a longstanding bottleneck, since rapid de‐excitation is usually accompanied by excessive exciton localizat...
