LUMINISCENT GLASS (VERSIONS) Russian patent published in 2014 - IPC C03C3/15 C03C4/12 

FIELD: chemistry.

SUBSTANCE: invention relates to optic materials, in particular to melt alumoborate glass, activated by trivalent ions of cerium (Ce³⁺) and terbium (Tb³⁺), which can be used as a visualiser of ultraviolet images and light transformer from ultraviolet into the yellow-green area of the spectrum. Glass (versions) has the following composition, mol.%:B₂O₃ 55-70, Al₂O₃ 15-35, La₂O₃ 1-10, Ce₂O₃ 1-5, Tb₂O₃ 2-10 and over 100% Sb₂O₃ 0.5-5 or B₂O₃ 55-70, Al₂O₃ 15-35, Y₂O₃ 1-9, La₂O₃ 1-9, Ce₂O₃ 1-5, Tb₂O₃ 2-1 and over 100% Sb₂O₃ 0.5-5 or B₂O₃ 55-70, Al₂O₃ 15-35, Y₂O₃ 1-9, La₂O₃ 1-9, Ce₂O₃ 1-5, Gd₂O₃ 1-9, Tb₂O₃ 2-10 and over 100% Sb₂O₃ 0.5-5, or B₂O₃ 55-70, Al₂O₃ 15-35, Y₂O₃ 1-10, Ce₂O₃ 1-5, Tb₂O₃ 2-10 and over 100% Sb₂O₃ 0.5-5, or B₂O₃ 55-70, Al₂O₃ 15-35, Gd₂O₃ 1-10, Ce₂O₃ 1-5, Tb₂O₃ 2-10 and over 100% Sb₂O₃ 0.5-5, with the atomic ratio Tb/Ce≥1.

EFFECT: creation of glass with high active absorption in the ultraviolet area of the spectrum and efficient luminescence in the area of the maximal spectral sensitivity of the human eye.
