Carbon dots gels: synergistic platforms for advanced visual information storage

spatial patterning and temporal luminescence/deformation changes, particularly for high-security anti-counterfeiting and sensing. In this review, we systematically elucidate the underlying synergistic mechanisms of CDs gels composites, introduce their unique properties and application prospects in advanced information technologies, summarize the latest research progress, and discuss key challenges regarding interfacial interactions and cross-scale performance regulation for future development.
