Abstract
Abstract The glasses in PbF2–B2O3-REF3 (RE = Nd, Nd+La, Nd+Lu) system have been synthesized. The initial glasses were doped with several RE's (0.2–3.0 at%), one of which had no luminescent f–f transitions (La, Lu) and performed only the function of the stabilizer of the cubic phase PbF2, and the other (Nd) played the role of a luminescence center. Glass-ceramics have been obtained by the controlled crystallization of glasses with formation of Pb1-xLa/NdxF2+x or Pb1-xLu/NdxF2+x solid solutions. The luminescence spectra of co-activated glass-ceramics as well as crystalline samples demonstrated a splitting of the «0–0» line for the 4F3/2→4I9/2 transition. It has been shown that it is possible to stabilize a cubic phase based on PbF2 by several RE co-doping and to obtain glass-ceramics with a crystalline phase in which the concentration quenching was reduced compared to glass-ceramics doped with a single activator.
