Anti-counterfeiting safety method and device using quantum dots

Abstract

The invention provides an anti-counterfeiting safety method and device using quantum dots. The anti-counterfeiting safety device comprises a base, a plurality of grooves and a plurality of quantum dotoptical pieces. After a short-wavelength colored light irradiates the plurality of optical parts, each optical part can emit a plurality of fluorescent lights; wherein each fluorescence comprises atleast one wavelength, and each fluorescence has a two-dimensional coordinate position, a fluorescence intensity integral area, a light color and a color gradation corresponding to the fluorescence. Particularly, a plurality of two-dimensional coordinate positions, a plurality of wavelength numerical values and a plurality of fluorescence intensity integral area numerical values are filled into a three-dimensional coordinate system to form a three-dimensional pattern; and simultaneously the plurality of two-dimensional coordinate positions, the plurality of light colors and the plurality of color gradation values are input into a two-dimensional coordinate system to present a two-dimensional color gradation pattern. Therefore, the two-dimensional color gradation pattern or the three-dimensional pattern is used as an information carrying label or a security verification label, so that the complexity of the anti-counterfeiting code can be greatly increased, and the purpose of improving the anti-counterfeiting security is achieved.

Description

technical field [0001] The present invention relates to the technical field of anti-counterfeiting labels and security verification, and in particular to an anti-counterfeiting security method and device using quantum dots. Background technique [0002] The implementation of anti-counterfeiting technology (Anti-counterfeiting technology) can be used to prevent infringers from imitating products without the permission of the owner. At present, anti-counterfeiting technology is divided into: printing anti-counterfeiting technology, chemical material anti-counterfeiting technology, physical anti-counterfeiting technology, digital information anti-counterfeiting technology, structure and packaging anti-counterfeiting technology. [0003] Quantum dot fibers and their fabrics have been developed as emerging anti-counterfeiting technologies. Chinese Patent Publication No. CN106245129A discloses a method for manufacturing quantum dot fibers, including the following manufacturing st...
