Abstract Optical encryption technologies based on room-temperature light-emitting materials are of considerable interest. Herein. we present three-dimensional (3D) printable dual-light-emitting materials for high-performance optical pattern encryption. These are based on fluorescent perovskite nanocrystals (NCs) embedded in metal-organic frameworks (MOFs) designed for phosphorescent h... https://darthomes.shop/product-category/shams/
