镧系金属有机框架材料在防伪中的应用OA

Information security and anti-counterfeiting technologies are essential for financial systems,commodity circulation,and public safety.However,traditional anti-counterfeiting strategies based on single and static optical features are increasingly insufficient against rapidly evolving counterfeiting techniques.Lanthanide metal-organic frameworks(Ln-MOFs),featuring high brightness,long decay lifetimes,narrow-band emissions,and tunable re-sponses to light,temperature,pH,and other stimuli,have emerged as ideal candidates for constructing multimodal optical security systems.This review summarizes the luminescence mechanisms,structural design principles,and stimulus-responsive regulation strategies of Ln-MOF,and highlights their representative applications in multi-level encrypted labels,dynamic QR codes,and composite anti-counterfeiting platforms.Key challenges related to stabili-ty,intelligence,and tapping the potential of pore channels are discussed,and future development directions of Ln-MOFs in advanced anti-counterfeiting and information storage technologies are outlined.
