 The bottom-up synthesis method remains the most widely used route for large-scale and low-cost production of carbon dots, CDs, but recent advancements have led to a new classification of CDs called carbonized polymer dots, CPDs, with unique polymers slash carbon hybrid structures and properties. The synthesis methods, structure slash property features, formation process, and nucleation mechanism of CPDs are comprehensively discussed, providing insights into their potential applications in various fields.
