Phosphor-in-glass with time-evolving multicolor luminescence for dynamic anticounterfeiting
The conventional luminescent materials used in the anticounterfeiting field generally exhibit unicolor output and a single-wavelength excitation mode, resulting in a poor anticounterfeiting effect. Herein, we successfully achieved a new transparent SrAl _2 O _4 :Eu ^2+ ,Dy ^3+ /CaAlSiN _3 :Eu ^2+ ph...
