Fig. 2: X-ray diffraction patterns measured at ID09 beamline, ESRF.
a The 2D azimuthal unfolded pattern of the diffraction image on the stripe type Ti3O5 pellet. b–d Results of Rietveld refinement of the 1D pattern for the block, stripe and flake type Ti3O5 respectively. Measured powder pattern is plotted in gray dashed line, calculated patterns are in red b (block type), yellow c (stripe type) and green d (flake type). Orange and blue curves are the contribution of the λ and β-phase respectively. Labels are shown only for the most intense peaks and not when too many overlap. The residual curve is shown as a grey dotted line. e 1D diffraction patterns measured for the photoexcited stripe type Ti3O5 pellet at different time delays. The shift in the peak (110) is shown in the inset. The arrows indicate the increase or decrease in the peak intensity with delays. f The differential diffraction patterns for the same delays to follow the photoinduced structural changes. The blue and orange dashed vertical lines in subfigure e and f mark the positions of the β and λ-phase peaks respectively. Only selected intense peak labels are indicated in the plot.
