摘要

碳点(CDs)由于其出色的光学性能、高生物相容性和低毒性，因此在许多领域都具有潜在应用。对其光致发光(PL)机制的认识已得到广泛研究，对于指导可调节PL发射的CDs的合成和推广应用具有重要意义。但是，PL发射的内在机理尚不清楚，并且由于颗粒结构的差异，尚未找到统一的机理。本综述根据对结构和性能特征的分析，总结了一种新的CDs分类，称为碳化聚合物点(CPDs)。概述了与结构差异有关的三种PL机制:内部因素主导发射(包括共轭效应、表面状态和协同效应)、外部因素主导发射(包括分子态和环境效应)以及交联-发射增强。除此之外，还简要介绍了CDs的光学应用。最后，讨论了PL机制的研究前景，并指出了未来工作中存在的挑战和方向。

Abstract

Carbon dots(CDs) may be useful in many fields due to its excellent optical properties

high biocompatibility and low toxicity. The knowledge of its photoluminescence(PL) mechanism has been extensively studied

which is of great significance for guiding the synthesis and popularization of CDs with adjustable PL emission. However

the internal mechanism of PL emission is still unclear

and due to the difference in particle structure

a unified mechanism has not yet been found. This review summarizes a new CDs classification based on the analysis of structural and performance characteristics

called carbonized polymer dots(CPDs). Three PL mechanisms related to structural differences are summarized: internal factors dominate emission(including conjugation effects

surface state and synergistic effects)

external factors dominate emission(including molecular state and environmental effects)

and cross-linking-emissions. The optical application of CDs is also briefly introduced. Finally

the prospects for research into PL mechanisms are discussed

noting the remaining challenges and directions for future work.
