Figure 3
Simultaneously taken XRD and XRS data of a polycrystalline CeO2 sample in pellet form. (a) Stitched miniXRD detector image from the ambient temperature data shown in panel (b). (b) XRD data for CeO2 at ambient temperature (RT) and T = 700°C after azimuthal integration and the result of a Rietveld refinement at T = 700°C. (The small peaks around 2θ = 20°, 21° and 49° are due to diffraction from the sample holder used.) (c) Ce N4,5 excitation spectra measured using X-ray Raman scattering spectroscopy at a momentum transfer of q = 9.3 Å−1. |
