Water-sensitive multicolor luminescence in lanthanide-organic framework for anti-counterfeiting

The development of high-level anti-counterfeiting techniques is of great significance in economics and security issues. However, intricate reading methods are required to obtain multi-level information stored in different colors, which greatly limits the application of anti-counterfeiting technology...
