Journal ArticleDOI
On the origin of near-IR luminescence in Bi-doped materials (II). Subvalent monocation Bi+ and cluster Bi5(3+) luminescence in AlCl3/ZnCl2/BiCl3 chloride glass
Alexey N. Romanov,Z. T. Fattakhova,Alexander Veber,O. V. Usovich,E. V. Haula,Vladimir N. Korchak,Vladimir B. Tsvetkov,Lev A. Trusov,Pavel E. Kazin,Vladimir B. Sulimov +9 more
TL;DR: Broadband NIR photoluminescence (from 1000 to 2500 nm) was observed from partially reduced AlCl₃/ZnCl ₂/BiCl⁂/ bi₅³⁺ glass, containing subvalent bismuth species.
Journal ArticleDOI
Spectral properties and NIR photoluminescence of Bi+ impurity in CsCdCl3 ternary chloride
Alexey N. Romanov,Alexander Veber,Z. T. Fattakhova,D. N. Vtyurina,Mikhail S. Kouznetsov,Ksenia S. Zaramenskikh,Igor S. Lisitsky,Vladimir N. Korchak,Vladimir B. Tsvetkov,Vladimir B. Sulimov +9 more
TL;DR: In this paper, the absorption spectrum is assigned to optical transitions of A → E type in two nonequivalent Bi + positions of D 3h and C 3v symmetry and the possibility of Jahn-Teller effect in Bi + excited states of E type is discussed in relation with absorption and luminescence excitation spectra properties.
Journal ArticleDOI
Near-IR luminescence from subvalent bismuth species in fluoride glass
Alexey N. Romanov,E. V. Haula,Z. T. Fattakhova,Alexander Veber,Vladimir B. Tsvetkov,Denis M. Zhigunov,Vladimir N. Korchak,Vladimir B. Sulimov +7 more
TL;DR: In this article, the broadband NIR luminescence of subvalent bismuth species was demonstrated in partially reduced ZrF 4 -BiF 3 -NaF and Zr F 4 -BaF 2 fluoride glasses.
Journal ArticleDOI
Effect of thermally induced structural disorder on the chemical durability of International Simple Glass
Frédéric Angeli,Thibault Charpentier,Patrick Jollivet,Dominique de Ligny,Michael Bergler,Alexander Veber,Stéphane Gin,Hong Li +7 more
TL;DR: Angeli et al. as mentioned in this paper investigated the structural changes induced by fast quenching of borosilicate glass and their effects on chemical durability by varying the thermal history of the glass.
Journal ArticleDOI
Subvalent bismuth monocation Bi+ photoluminescence in ternary halide crystals KAlCl4 and KMgCl3
Alexey N. Romanov,Alexander Veber,Z. T. Fattakhova,O. V. Usovich,E. V. Haula,Lev A. Trusov,Pavel E. Kazin,Vladimir N. Korchak,Vladimir B. Tsvetkov,Vladimir B. Sulimov +9 more
TL;DR: In this paper, the 6p 2 open-shell electronic configuration of the Monocation Bi + was used to produce long-lived NIR photoluminescence in ternary chloride crystals.
