Several Fe-B-Si-P-Nb-Cr amorphous metallic glasses were produced by a melt spinning technique. The structure, thermal stability and crystallization processes of amorphous alloys were studied. The size distributions of inhomogeneities of both initial and annealed samples were determined.
Transparent glass-ceramic materials containing PbWO4 crystalline phase were fabricated during heat treatment of lead borate glasses singly doped with Dy3+ and Er3+ ions. Luminescence spectra of lanthanide ions in precursor glasses and glass-ceramics were examined under different excitation wavelengths. Strengthening and broadening blue bandwidth linked with 4F9/2 → 6H15/2 transition of Dy3+ were observed...
