摘要：

There is a pressing need for an ultra-long-lasting, dynamic fluorescent anti-counterfeiting label to address the issue of cargo switching during ocean shipping. To this end, we have successfully developed time-dependent anticounterfeiting labels based on hybrid perovskite halogen separation. The fluorescence of the in situ prepared CsPb(BryI1-y)3@polyvinylidene (PVDF) films clearly changed irreversibly from red to orange and finally to green within two weeks. Our findings suggest that CsPb(BryI1-y)3@PVDF could serve as a promising material for fluorescent anti-counterfeiting. Furthermore, we designed a fluorescent anti-counterfeiting tag that leverages the unique fluorescence characteristics of CsPb(BryI1-y)3@PVDF to enable advanced dynamic information encryption.
