AI Technical Summary
Existing optical anti-counterfeiting materials are unstable, unfriendly, and can only achieve single-mode anti-counterfeiting, lacking highly stable and multifunctional materials.
A novel organic-inorganic hybrid doped zirconium-based perovskite single crystal was prepared by mixing tetraethylammonium chloride, zirconium tetrachloride, antimony trioxide or bismuth trioxide with polydimethylsiloxane to prepare (TEA)2ZrCl6:Sb or (TEA)2ZrCl6:Sb/Bi single crystals for use in the preparation of anti-counterfeiting materials.
The prepared zirconium-based perovskite single crystal has multicolor luminescence properties. The anti-counterfeiting material prepared using it emits different colors under 254nm and 365nm ultraviolet light excitation. It has stability and flexibility, and the preparation method is simple and low-cost, making it suitable for large-scale production.
