All-inorganic perovskites for four-dimensional dynamic encryption

In an era marked by increasing demand for advanced anticounterfeiting measures, we introduce a four-dimensional (4D) dynamic physical unclonable function that uses defect-engineered photoluminescence blinking in all-inorganic CsPbBr3 perovskite quantum dots (QDs) embedded within a polymethylmethacrylate matrix. Even wi...
