Abstract
Oxyfluoride silicate glasses in the SiO2-Al2O3(AlF3)-CdF2-PbF2-ZnF2-Eu2O3 system are studied. Glass-ceramic materials with special properties promising for use of these glass-ceramics as active optical media are synthesized from the oxyfluoride glasses under investigation. The physicochemical and spectral-luminescence properties of the glass-ceramic materials synthesized are investigated. It is shown that the composition of glasses and, consequently, their thermal and physical properties depend on the synthesis conditions. Heat treatment of glasses doped with Eu3+ ions at temperatures somewhat higher than the glass transition point T g leads to the formation of β-PbF2 nanocrystals such that the major part of the dopant enters into the nanocrystal composition.
