Abstract

We have investigated the samples of thermally treated oxyfluoride glass ceramics 50SiO₂-25LiO₂-20YF₃-3ErF₃-2YbF₂ by means of electron paramagnetic resonance (EPR) techniques. After irradiation of the samples with X-rays, in the EPR spectra a hyperfine structure characteristic of F-centres could be observed in different fluoride crystals. The structure of F-centre in the oxyfluoride glass ceramics containing LiYF₄ crystallites is discussed.
