Fig. 2: XAS spectra of 20 nm TiO2 NC at the oxygen K-edge and the Ti L-edge.

From: Direct and real-time observation of hole transport dynamics in anatase TiO2 using X-ray free-electron laser

a Overview of the oxygen K-edge XAS measured +1 ps after the pump excitation (black) and the ground states before excitation (red). Simulated XAS (orange) and O pDOS (green) are well matched with measured XAS at the oxygen K-edge. The transient XAS spectrum at +1 ps is multiplied by 5 times. (blue) (inset) ground state XAS spectra for SC and NC at the oxygen K-edge. b Overview of the Ti L-edge XAS measured +1 ps after the pump excitation (black) and the ground states before excitation (red) for anatase TiO2 NC. The transient XAS spectrum at +1 ps (blue) consists shift-induced component (green) and the other component (pink). The transient XAS spectrum at +100 ps (cyan) does not show shift induced component. (inset) ground state XAS spectra for SC and NC at the Ti L-edge. Error bars correspond to the standard errors.
