Tags: National Tsing Hua University, Taiwan, Science & Exploration, Electronics & Robotics
This technology introduces an anti-counterfeiting method using quantum dots to create unique, secure labels. By illuminating quantum dot components, they emit varied fluorescences, recorded as a two- or three-dimensional pattern. These patterns serve as complex, difficult-to-replicate security labels for products. Applications include enhancing security in product packaging and documents. This method significantly boosts anti-counterfeiting measures by utilizing the distinctive properties of quantum dots.
