Nitrogen and fluorine co-doped carbon dot holographic anti-counterfeiting aluminum foil and preparation method thereof

The invention particularly relates to a nitrogen and fluorine co-doped carbon dot holographic anti-counterfeiting aluminum foil and a preparation method thereof. An aluminum foil layer is sequentially provided with a dry type transfer glue layer, an aluminum plating layer, a shielding layer, a holographic information layer, a holographic imprinting coating, a carbon dot fluorescent coating and a surface coating from inside to outside. The method comprises the following steps: 1) preparing a carbon dot fluorescent coating; 2) a carbon dot fluorescent coating; (6) aluminum plating; 7) compounding; 8) transferring; and (9) surface coating. The anti-counterfeiting aluminum foil has the following advantages: 1) the fluorine atom doped carbon dot fluorescent anti-counterfeiting technology and the holographic anti-counterfeiting technology are combined on the anti-counterfeiting aluminum foil, so that the anti-counterfeiting means are enriched, and the anti-counterfeiting performance is improved; 2) the fluorescence
