Dynamic Electro‐Fluorochromic Device Based on Aggregation‐Induced Emission Carbon Dots and Prussian Blue for Anti‐Counterfeiting
Abstract Electro‐fluorochromic (EFC) dual‐functional materials have attracted remarkable attention due to their feature about two distinct display modes. Carbon dots (CDs) stand out as a tunable photoluminescent materials. The pursuit of tunability controlled by electricity in dynamic devices remains a challenging goal. In this study, an EFC material is developed based on electrochromic (EC) Prussian blue (PB) and aggregation‐induced emission CDs, utilizing an energy transfer mechanism to achieve synergistic dynamic modulation. The CDs/PB film exhibited reversible optical responses while maintaining an excellent EC performance of PB with a stable cycling performance over 2000 cycles and a fast response speed. This material shows a promising potential for advanced display technologies, interactive interfaces, and anticounterfeiting applications. These findings provide a valuable strategy for the development of multifunctional dynamic devices and sensors.
