Abstract

The article presents the use of Eu³⁺ ions as a spectroscopic probe to measure changes in glass structure without interfering with the tested material. The aim of the work is to obtain bioactive glass-ceramics structure with increased mechanical properties. Examined 45S5 Bioglass® was annealed at 620°C for 8h. XRD measurements indicate the formation of the glass-ceramics structure with nanocrystals (Na₄CaSi₃O₉). Despite the additional heat treatment, the bioactivity of the glass has been preserved. The changes of luminescence profile of Eu3^{+ -}doped glass was determined. Decreasing value of fluorescence intensity radio parameter after annealing indicates symmetry around europium ions and thus the arrangement of the glass structure.
