Patent ID: 10713977

Abstract:
Disclosures of the present invention describe an anti-counterfeit security verification method and device using quantum dots, wherein the anti-counterfeit security verification device consists of a base, a plurality of receiving recesses formed on the base, and a plurality of optical members. After being illuminated by a short-wavelength light, the optical members irradiate a plurality of photoluminescent light, and each of the photoluminescent lights comprises at least one wavelength value, one (x, y) coordinate position, one value of integrated photoluminescence intensity area, one photoluminescence color, and one color scale value. Particularly, the present invention develops a 3D pattern and a 2D color-scale pattern in a three-dimensional coordinate system and a two-dimensional coordinate system, such that the 2D color-scale pattern and the 3D pattern are respectively used as an information carrying label and a security verification, or respectively adopted as the security verification and the information carrying label.
