專利摘要(英)
The present invention mainly discloses an anti-counterfeit security verification method and device using quantum dots, wherein the novel device comprises: a base, a plurality of receiving recesses formed on the base, and a plurality of QD optical elements. After using a short-wavelength light to irradiate the plurality of QD optical elements, the plurality optical elements individually radiate a plurality of photoluminescent lights. Wherein each of the plurality of photoluminescent lights comprises at least one wavelength, and has a corresponding two-dimensional coordinate position, integral area of photoluminesce intensity, photoluminesce color, and color-level of the photoluminesce color. Particularly, the present invention fills in a three-dimensional coordinate system with the two-dimensional coordinate position, the plurality of wavelength value, and the value of integral area of the fluorescence intensity for constituting a three-dimensional pattern, and also fills in a two-dimensional coordinate system with the two-dimensional coordinate position, the photochromic, and the value of color-level for displaying a two-dimensional level pattern. Thereof, by taking the two-dimensional level pattern or the three-dimensional pattern as a message-carrying label or a security verification label, it is able to substantially increase complexity of anti-counterfeit code so as to enhance the anti-counterfeit security.
