| titleOfInvention | Adjustable dual-mode composite fluorescent material and preparation method and anti-counterfeiting application thereof |
| abstract | The invention discloses a tunable dual-mode composite fluorescent material, a preparation method and an anti-counterfeiting application thereof 2+ Preparation of { [ Cd ] by coordination of ion and tetracarboxylic acid ligand 4 (L) 2 (H 2 O) 3 ]·4.5H 2 O} n The metal-organic framework material of (1); the preparation method comprises the following steps: dissolving a cadmium source, a tetracarboxylic acid ligand and polyvinylpyrrolidone in a mixed solution of N, N-dimethylformamide and water, heating and refluxing for 3 days at 80 ℃ to obtain colorless crystals, collecting and drying to obtain the metal organic framework material with the three-dimensional structure. The invention further prepares the adjustable dual-mode composite fluorescent material on the basis, the mixture of the composite fluorescent material solution is used as the anti-counterfeiting ink, signals and pictures are written and drawn on paper, photoluminescence conversion can be repeatedly realized, and the display shows thatIts versatility and great potential for raising anti-fake level. |
