✦ Synopsis

Structural, thermal and optical properties of Eu-doped lead fluoroborate glasses have been investigated as a function of PbF 2 concentration. The values of the phonon energy of the host, the glass transition temperature and the fluorescence intensity ratio of the 5 D 0 -7 F 2 to 5 D 0 -7 F 1 transition of Eu ions considerably decrease, whereas 5 D 0 luminescence lifetime slightly increases with increasing PbF 2 concentration. Incorporation of PbF 2 results in structural and spectroscopic changes around Eu 3C ions and surrounding ligands, which were analyzed in detail using by Raman, IR, DSC and photoluminescence (PL) spectroscopy.
