XANES analysis of phosphate glasses melted with Tb₄O₇ and SnO: evaluating the impact of valence states on structural, thermal, and luminescent properties

Abstract

Barium phosphate glasses were prepared with 0.5 mol% Tb4O7 added alongside SnO up to 5 mol% with the purpose of evaluating the resulting terbium and tin oxidation states and their impact on glass structural, thermal, and luminescent properties.
