Abstract

The photoluminescence of SiO₂-Al₂O₃-LiO₂-LaF₃ oxyfluoride glass and glass ceramic samples doped with Ce³⁺, Eu²⁺ and Ce³⁺/Eu²⁺ is investigated, and the spectra and fluorescence intensities are compared. The luminescence of samples activated by Eu ions is found to be more intensive than of the samples doped with Ce or Ce/Eu. The luminescence of glass ceramics is higher than that of the corresponding glass, which indicates that a proportion of the activator ions are embedded in the fluoride crystallites.
