• PHOTOLUMINESCENCE

Crystal-glass phase transition in luminescent metal halides provides unique opportunities to tune the photoluminescence. Here we report four zero-dimensional Sb-based halide glasses featuring reversible phase transition upon heating and acetone triggering conditions, along with modulated luminescence properties. Benefiting from the fluorescence switching, information encryption and anti-counterfeiting applications are achieved. @@@ Reversible crystal-glass phase transitions of several Sb-based halides and their switching luminescence were reported, and information encryption and anti-counterfeiting applications were achieved.
