Lead-barium fluoroborate glasses doped with Eu3+ have been synthesized. Using the heat-treatment we made glass-ceramics were building into fluoride crystal nanoparticles homogeneously distributed in the borate glass. The changes in the structural and optical properties of the glass-ceramics comparatively to initial glasses and polycrystalline fluoride containing Pb, Ba and Eu were revealed by X-ray diffraction and luminescence spectroscopy.
