Abstract

Abstract: The generation of silver species has been investigated in silver‐containing sodo‐gallo‐phosphate glasses subjected to X‐ray irradiations. Radioluminescence spectroscopy has evidenced the presence of isolated and paired silver ions. The proportion of silver pairing is found dominant in ortho‐phosphate glass compositions, compared to poly‐phosphate counterparts. The phosphate glass network is reported to have a decisive impact on X‐Ray photosensitivity and the formation of luminescent silver species, namely Ag 2+ hole trap silver ions and Agm x+ silver clusters. The subsistence of femtosecond laser produced silver luminescent structures under X‐Ray irradiation has been demonstrated.
