Fig. 4: Gain-switching characteristics of output pulses in CsPbBr3 microwires.
a Delay time and pulse width of optical pulse at 60 μJ cm−2 with respect to wavelength. The error bars that represent the standard deviation from the mean are too small to be visible. The inset shows the streak camera image at 60 μJ cm−2. b Normalized log-log plots of gain-switched pulse waveforms in Fig. 3. An exponential model (gray solid lines) fits well to the experimental data. The excitation energy-dependent delay time (red squares), rise time (circles), pulse width (diamonds) (c) and decay time (black squares) (d) of gain-switched pulses. The error bars here are too small to be visible. Dashed curves show the simulation results.
