A-Site Cation Engineering of CsPbBr3 Nanocrystals: Correlating Lattice Microstrain, Optical Properties, and Photodetector Performance
All-inorganic cesium lead bromide (CsPbBr3) nanocrystals (NCs) have recently attracted extensive attention due to their high photoluminescence quantum yield (PLQY), tunable bandgap, and promising applications in photodetectors. However, the stability of photodetector devices is still limited by the defect states, lat...
