摘要: Carbon-based quantum dots (CQDs), including spherical carbon and graphene dots, are an emerging class of photoluminescent (PL) materials with unique properties. Great progress has been made in the design fabrication high-performance CQDs, however, challenge developing solid-state PL CQDs have aroused great interest among researchers. A clear mechanism is basis for development light emission also a prerequisite realization multiple practical applications. However, extremely complex structure CQD greatly limits understanding CQDs. So far, variety models proposed to explain but they not unified. This review summarizes current from perspective energy band theory electronic transitions. In addition, common strategies realizing summarized. Furthermore, applications fields light-emitting devices, anti-counterfeiting, fingerprint detection, etc., proposed. Finally, brief outlook given, highlighting problems, directions
