Oxide glass

Aiming at applications to opto-electronic integrated devices, we have prepared n-type oxide bulk glasses composed only of non-toxic elements. The fluorine-doped Fe₃O₄–Bi₂O₃–B₂O₃ glass exhibited a room-temperature conductivity of ~10^-2 S/cm, while the WO₃–P₂O₅ glass prepared under a hydrogen-reducing atmosphere showed a much higher value of ~10 S/cm. Both glasses exhibited n-type conductivity.
