Abstract

It was demonstrated, that broadband NIR luminescent bismuth species can be prepared by synproportionation reaction of Bi metal and bismuth ions in usual oxidation state +3. This reaction was observed in highly Lux-Flood oxoacidic borate or phosphate glass melts [1], and Lewis acidic chloroaluminate ionic liquid [2]. The various subvalent Bi species, like univalent cation Bi + and polycation clusters (Bi53+, Bi 82+ etc.) were considered as possible products of synproportionation 2Bi + Bi3+ 3Bi+ or 4Bi + Bi 3+ Bi53+ and candidate NIR luminescent species. The equilibrium shifted toward subvalent species by increasing acidity or/and temperature.
