Humidity and ultraviolet modulate color turned LnNa-based metal-organic frameworks as Bi-decryption anti-counterfeit materials

Dynamic multi-decryption with luminescent anti-counterfeit materials still presents a challenge in information storage and security. In this work, Gd 3+ is introduced into the structure of lanthanide-based metal-organic frameworks (LnMOFs) ([LnNa(HL 2 ) 2 (H 3 L 2 ) 0.5 ]·EtOH, H 3 L 2 = 5-hydroxy-i...
