Abstract The smart materials with multi‐color and stimuli‐responsive luminescence are very promising for next generation of optical information encryption anti‐counterfeiting, but these still scarce. Herein, a multi‐level strategy is developed based on the polychromatic emission Sb‐doped double perovskite powders (SDPPs). Cs 2 NaInCl 6 :Sb, KInCl AgInCl :Sb synthesized through coprecipitation methods exhibit broadband emissions bright blue, cyan, orange colors, respectively. transmitted by specific SDPP encrypted when different SDPPs mixed. confidential can be decrypted selecting corresponding narrowband filter. Then, an quick response (QR) code improved security demonstrated this multi‐channel selection strategy. Moreover, three types water‐triggered switching behaviors. represented erased/recovered simple water spray/drying. Whereas, collected from green channel permanently erased moisture, which fundamentally avoids leakage. Therefore, schemes designed to meet variety requirements. multicolor greatly enrich flexibility encryption, leaps level confidentiality.

Abstract Counterfeit products and data vulnerability present significant challenges in contemporary society. Hence, various methods technologies are explored for anticounterfeiting encoding, with luminescent tracers, particularly carbon dots (CDs), emerging as a notable solution. CDs offer promising contributions to product security, environmental sustainability, the circular economy. This critical review aims highlight luminescence responsiveness of physical chemical stimuli, achieved through nanoengineering their structure. The discussion will delve into tunable mechanisms decay times CDs, investigating preferential excitations such up‐conversion, delayed fluorescence, room temperature phosphorescence, persistent luminescence, energy charge transfer, well photo‐chemical interactions. These insights crucial advancing solutions. Following this exploration, systematic focus on research CDs' smart encoding applications, encompassing anticounterfeiting, tracing, quality certification, information encryption. Finally, address key implementing CDs‐based technology, providing specific strategies aimed at maximizing stability efficacy applications.
