Figure 5

The time-resolved PL decay curves of a 3 mm thick high quality MAPbBr3 single crystal (SC) measured under reflection mode with photomask (black dot) and transmission mode (red dot); The inset shows the schematic of the measurement geometry of the reflection mode (left panel) and transmission mode (right panel); During the measurement, a 568 nm band-pass filter with band width of 10 nm was placed in front of the detector, in order to restrict the measurement wavelength range.
