Lead-barium fluoroborate (PbF 2 -BaF 2 -B 2 O 3 ) glasses doped with RE (Nd 3+ or Er 3+ ) were synthesized and researched. Glass-ceramics, where the ions RE are hosted by fluoride crystal nanoparticles embedded in borate glass, made by heat-treatment. The changes in the structural and optical properties of the glass-ceramics comparatively to initial glasses were revealed by X-ray diffraction, Raman spectroscopy and luminescence spectroscopy of RE ions. Spectral properties of polycrystalline fluoride containing Pb, Ba and RE are investigated also.
