a Normalized TA spectra around the peak at 406 nm under different pump fluences with λp = 320 nm. b Kinetic profiles of 395 nm bleach under different pump fluences. c Normalized TA spectra at different time delays (Fp~0.13 mJ/cm2), with the high energy tails (between 3.1 and 3.4 eV) fitted by an exponential function corresponding to Maxwell–Boltzmann distribution to extract the hot carrier temperature TC. d The obtained TC as a function of time delay.
