摘要
Recently,persistent luminescence materials(PLMs)have attracted extensive attention in the anti-counterfeiting and information encryption fields.Unfortunately,single visible persistent luminescence(PersL)demonstrates limited information security because the changes in information coded by visible PersL can be observed by the human eyes.In this work,we develop a dual-mode PLM with ultraviolet(UV)and visible PersL.
