Abstract

The broadband NIR luminescence of subvalent bismuth species was demonstrated in partially reduced ZrF4-BiF3-NaF and ZrF4-BiF3-BaF2 fluoride glasses. The parameters of luminescence were reported and compared with luminescence from other bismuth-doped materials. Since fluoride glass compositions are based on strong Lewis acids (ZrF4 in present case) they can stabilize NIR photoluminescent subvalent bismuth species.
