Oxyfluoride lead borate glasses singly doped with Nd(3+) and Er(3+) ions have been studied before and after thermal treatment. The orthorhombic PbF(2) crystallites are formed during thermal treatment, which was evidenced by X-ray diffraction analysis. Near-infrared luminescence spectra at 1.06 mu m and 1.53 mu m have been registered for samples before and after annealing, which correspond to the main (4)F(3/2)-(4)I(11/2) and (4)I(13/2)-(4)I(15/2) laser transitions of Nd(3+) and Er(3+) ions, respectively. Luminescence decays from (4)F(3/2) state of Nd(3+) and (4)I(13/2) state of Er(3+) have been analyzed in detail. Contrary to Nd-doped samples, the luminescence lines obtained for Er-doped transparent oxyfluoride glass-ceramics are more intense and narrowed, whereas the luminescence decays from (4)I(13/2) state of Er(3+) are slightly longer in comparison to precursor glasses.
