Temporal response of mode switching in perovskite microrod. a Output intensity of perovskite microrod by different pulses. Inset: the SEM image, where the length of scale bar is 10 μm. b Mode intensity as a function of delay time. c Relative intensity of the two modes (mode-1/mode-2) as a function of delay time
