<abstract xmlns="http://www.w3.org/1999/xhtml"> 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.</abstract>
