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 transit

## Abstract Dy^3+^ doped lead fluoroborate (LFB) glasses (B~2~O~3~β+βPbOβ+βPbF~2~) have been prepared following conventional melt quenching technique by varying the concentration of Dy~2~O~3~ in the order 0.01, 0.1, 1, 2, and 3βmol%. Xβray powder diffraction (XRD), Fourier transform infrared (FTIR)
A series of Er 3+ -doped 50Bi 2 O 3 -(50-x)B 2 O 3 -xGeO 2 +0.5 wt% Er 2 O 3 (x ΒΌ 0, 5, 10, 15, 20 mol%) glasses were prepared. The thermal stability, absorption spectra, emission spectra and lifetime of the 4 I 13/2 level of Er 3+ ions were measured and studied. It is found that the absorption cros
