XANES measurement is sometimes the only available technique for the evaluation of the valence state of a dopant cation, which often occurs in phosphor materials. The validity of the core excitation process should be examined as a basis for understanding the applicability of this technique. Here, we demonstrate the validity of valence estimation of tin in oxide glasses, using Sn K-edge and L-edge XANES spectra, and compare the results with ¹¹⁹Sn Mössbauer analysis. The results of Sn K-edge XANES spectra analysis reveal that this approach cannot evaluate the actual valence state. On the contrary, in L_II-edge absorption whose transitionScientific reports415https://www.ebi.ac.uk/biostudies/studies/S-EPMC5764964biostudies-literatureValidity of Valence Estimation of Dopants in Glasses using XANES Analysis.PMC5764964Mibu KMasai HIna TOkumura SfalseValidity of Valence Estimation of Dopants in Glasses using XANES Analysis.X-ray absorption near edge structure (XANES) measurement is one of the most powerful tools for the evaluation of a cation valence state.
