Pressure‐Induced Indirect‐Direct Bandgap Transition of CsPbBr(3) Single Crystal and Its Effect on Photoluminescence Quantum Yield

Despite extensive study, the bandgap characteristics of lead halide perovskites are not well understood. Usually, these materials are considered as direct bandgap semiconductors, while their photoluminescence quantum yield (PLQY) is very low in the solid state or single crystal (SC) state. Some rese...
