Fig. 3: Normalised Zr K-edge XANES spectra of the 5 mol% Am-doped ZrO₂ sample.

Normalised Zr K-edge XANES spectra of the 5 mol% Am-doped ZrO₂ sample with a m-Zr⁺⁴O₂ standard. The vertical dashed black line corresponds to the white line position of the m-Zr⁴⁺O₂ standard, representing the reference Zr⁴⁺ oxidation state.
