摘要

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/Nd(3)F(2+)3 solid solutions. The luminescence spectra of co-activated glassceramics as well as crystalline samples demonstrated a splitting of the "0-0" line for the F-4(3/2) -> I-4(9/2) 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 glassceramics doped with a single activator.
