Abstract:Mn2+ and Sn2+ co-doped Cs3ZnI5 crystals synthesized via gradient cooling crystallization are used for fluorescence anticounterfeiting. It exhibits excitation-wavelength dependence and utilizes a matrix operation strategy for information encryption.
Dynamic luminescence materials overcome the disadvantage of traditional static anti-counterfeiting materials that are easy to imitate, but the repeated display of dynamic luminescence is still a challenge. In this work,...
