Triple-Mode Glow to Fight Counterfeiting

Ink with carbon nanodots luminesces via three different mechanisms.
Banknotes, documents, branded products, and sensitive goods like pharmaceuticals or technical components are often marked to distinguish them from imitations. However, some counterfeiters have learned to copy conventional fluorescent tags. In the journal Angewandte Chemie, Chinese scientists have now introduced a new, exceptional anti-counterfeit ink made with carbon nanodots. Their ingenious composite material emits three different types of luminescence.
