Abstract

In this paper, the impact of the post-heat-treatment on the structural and spectroscopic properties as well as on the chemical durability of a thermally stable Er³⁺-doped phosphate glass in the system P₂O₅ - K₂O - Al₂O₃ - B₂O₃ - BaO - PbO - La₂O₃ - Gd₂O₃ is reported. Two crystalline phases, namely La, Gd-monazite and AlKP₂O₇, were found to precipitate from the surface of the glass after heat-treatment, as confirmed by both X-ray Diffraction (XRD) and Scanning Electron Microscopy/Energy Dispersive X-ray (SEM/EDX) analyses. Moreover, the heat-treatment was responsible for the formation of a more polymerized glass network close to the surface crystalline layer as evidenced using micro-Raman spectroscopy. From the changes in the Er³⁺ optical properties, some of the Er³⁺ ions are suspected to enter in the crystals. Both the as-prepared and heat-treated glasses were subjected to a degradation test in hydrochloric acid (HCl) and showed a congruent and incongruent dissolution behavior, respectively.
