| Abstract | ||
| Counterfeiting causes loose of trillions of dollars annually. It harms the personal safety by using fake components like electronic products. According to the world health organization more than 50% of medical products are not genuine which affects people’s health leading to large number of deaths. Security inks with luminescence characteristics have great interest in anticounterfeiting applications. Providing simple, highly secure and price-effective luminescent inks has been a major challenge for anticounterfeiting applications. The promising optical characteristics of long-persistent photochromic nanocomposites may pave the way for advanced anticounterfeit materials. | ||
