MAPbBr3 Quantum Dots Encapsulated Within Lanthanide‐MOFs for Time‐Resolved Multicolor Dynamic Anticounterfeiting

@Eu-MOFs can be modulated by varying UV excitation wavelengths, thereby conferring a spatially distinguishable anticounterfeiting dimension. The time-resolved unpredictability of these dynamic color changes coupled with sustained luminescent intensity and multi-dimensional anticounterfeiting, render them suitable system for advanced graphical coding. These findings pave the way for the advancement of intelligent multicolor dynamic optical anticounterfeiting.
