GLASS Russian patent published in 2018 - IPC C03C3/68 C03C3/72 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions of luminescent lead borosilicate glasses. Glass contains the following components, weight%: B₂O₃ 6.0–27.0; SiO₂ 3.0–10.0; Al₂O₃ 1.0–3.0; PbO 60.0–90.0 and at least one oxide from the group Pr₂O₃, Sm₂O₃, Nd₂O₃, Tb₂O₃, Ho₂O₃, Er₂O₃, Tm₂O₃, Eu₂O₃, Ce₂O₃ with the following component ratio, said oxide being introduced in excess of 100% (wt%): Pr₂O₃, Sm₂O₃ 1.0–10.0; Nd₂O₃. Tb₂O₃ 1.0–20.0; Ho₂O₃. Er₂O₃. Tm₂O₃ 1.0–10.0; Eu₂O₃ 1.0–15.0; Ce₂O₃ 0.1–10.0.

EFFECT: technical result is obtaining of a high quantum yield of luminescence of ions of rare-earth and transition elements.
