專利摘要(中)
本發明主要提出一種使用量子點的防偽安全方法與裝置，該防偽安全裝置包括：一基座、形成於該基座之上的複數個凹槽、以及複數個量子點光學件。以一短波長色光照射複數個所述光學件之後，各該光學件會發出複數螢光；其中，各該螢光包括至少一波長，且各該螢光具有與其相對應的二維座標位置、螢光強度積分面積、光色、與色階。特別地，本發明係將複數個所述二維座標位置、複數個波長數值、與複數個所述螢光強度積分面積數值填入一三維座標系統之中以構成一三維圖案，並同時將複數個所述二維座標位置、複數個所述光色、與複數個色階數值填入一二維座標系統之中以呈現一二維色階圖案。如此，以該二維色階圖案或該三維圖案作為一訊息攜載標籤或一安全驗證標籤的方式，便能夠大幅增加防偽編碼的複雜度，達到提升防偽安全性之目的。

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.
