## Abstract Dy^3+^ doped lead fluoroborate (LFB) glasses (B~2~O~3~ + PbO + PbF~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 3 mol%. X‐ray powder diffraction (XRD), Fourier transform infrared (FTIR)
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
