Transparent oxyfluoride nano-glass-ceramics 90(SiO 2 )10(PbF 2 ) co-doped with 0.3 Yb 3+ and 0.1 Er 3+ (mol%) have been prepared by thermal treatment of precursor sol-gel glasses. X-ray diffraction and high resolution transmission electron microscopy analysis pointed out a precipitation of cubic b-P
