Multicolor carbon dots‐based materials offer a variety of opportunities for potential applications in bioimaging, optoelectronic devices, and information security. In article number 2100421, Zifei Wang and co‐workers present a strategy for the first time based on thermally driven amorphous‐crystalline phase transition to achieve multicolor carbonized polymer dots (CPDs) with the emission color tunable from green to orange‐red. Potential application of the developed CPDs as printable and writable security inks for advanced multilevel anti‐counterfeiting and encryption is demonstrated.
