LUMINESCENT LEAD OXYFLUORIDE GLASS Russian patent published in 2024 - IPC C03C4/12 C03C3/112 C03C3/105

Abstract RU 2824890 C1

FIELD: glass.

SUBSTANCE: invention relates to luminescent lead oxyfluoride glass and can be used in making optical waveguides, optoelectric devices and quantum electronics devices. Glass composition, mol.%: (45)SiO₂-(40)PbF₂-(10)AlO_1.5-(3.49-x)ZnF₂-(0.5)TeO₂-(x)PbO-(0.01)Ag-(1)YbF₃, wherein 0.5≤x≤1.5.

EFFECT: invention allows to minimize the effect of glass remelting in the temperature range from 900 to 1,000 °C to photoluminescence intensity of silver nanoclusters and transparency of glass.
