## Description

- description: Thermodynamically metastable glasses that can contain metastable species
    are important functional materials. X-ray absorption near-edge structure (XANES)
    spectroscopy is an effective technique for determining the valence states of cations,
    especially for the doping element in phosphors. Herein, we first confirm the valence
    change of silver cations from monovalent to trivalent in aluminophosphate glasses
    by X-ray irradiation using a combination of Ag L3-edge XANES, electron spin resonance,
    and simulated XANES spectra based on first-principles calculations. The absorption
    edge of the experimental and simulated XANES spectra demonstrate the spectral
    features of Ag(III), confirming that AgO exists as Ag(I)Ag(III)O2. A part of Ag(I)
    changes to Ag(III) by X-ray irradiation, and the generation of Ag(III) is saturated
    after high irradiation doses, in good agreement with conventional radiophotoluminescence
    (RPL) behaviour. The structural modelling based on a combination of quantum beam
    analysis suggests that the local coordination of Ag cations is similar to that
    of Ag(III), which is confirmed by density functional theory calculations. This
    demonstration of Ag(III) in glass overturns the conventional understanding of
    the RPL mechanism of silver cations, redefining the science of silver-related
    materials.
