a 2D image of a differential transmission spectra (ΔT/T0) as a function of probe delay. The color bar shows the intensity of the ΔT/T0 with red and blue indicating positive and negative values, respectively. The plot at the bottom shows ΔT/T0 spectra at a delay of 0.3 ps. b Decay kinetics of monolayer MoS2 (black circles) and S-NEAPbI3/MoS2 heterostructure (blue circles) at 1.87 eV (shown by a dotted line in (a)). The solid lines are fit to mono-exponential decay function.
