Glasses of the composition (100-x-y)TeO2-PbO·P2O5-yPbF2-∶0.5EuF3 (x =42.5-30mol％, y =5-25 mol ％) have been investigated.It has been demonstrated that a glasslike network composed of mixed tellurite and phosphate polyhedra is formed in the glass: the network medium-range order area does not change significantly in the range of the examined compositions, despite changes occurring inside the network.Lead difluoride has a modifying effect on the structure of the glasslike network at large, i.e., both tellurite and phosphate groups.
