Subvalent bismuth monocation Bi+ photoluminescence in ternary halide crystals KAlCl4 and KMgCl3

Monocation Bi+ isomorphically substitutes potassium in KAlCl4 and KMgCl3 chlorides. Having the unique 6p2 open-shell electronic configuration, Bi+ possesses a number of low-lying excited states, and displays broadband long-lived NIR photoluminescence in ternary chloride crystals. ► Monocation Bi+ ca...

Description
Summary:Monocation Bi+ isomorphically substitutes potassium in KAlCl4 and KMgCl3 chlorides. Having the unique 6p2 open-shell electronic configuration, Bi+ possesses a number of low-lying excited states, and displays broadband long-lived NIR photoluminescence in ternary chloride crystals. ► Monocation Bi+ can isomorphically substitute K+ in ternary chloride crystals. ► Bi+ doped ternary chlorides can be crystallized from Lewis acidic melts. ► Bi+ doped ternary chlorides possess broadband NIR luminescence.
