The rapid and large‐scale production of carbon quantum dots and their integration with polymers

: Carbon quantum dots (CDs) have inspired vast interests due to their prominent photoluminescence (PL) performances and promising applications in optoelectronic, biomedical and sensing fields. Notably, the development of effective approaches for large-scale CDs production may greatly promote the further advancement of their practical applications. In this review, the newly emerging methods for the large-scale production of CDs are summarized, such as microwave, ultrasonic, plasma, magnetic hyperthermia and microfluidic technology. Then, we introduce the available strategies for constructing CDs/polymer composites with intriguing solid-state PL. Particularly, the multiple roles of CDs are emphatically presented, including fillers, monomers and initiators. Moreover, the typical applications of CDs/polymer composites in light-emitting diodes, fluorescent printing and biomedicine are outlined. Finally, we discuss their current problems and speculate on their future development.
