摘　　要：碳点(carbon dots,CDs)由于具有优异的荧光性能、低毒性、原料广泛、生物相容性好等优点,受到了研究人员的广泛关注。然而,目前大部分CDs的发射波长位于蓝光和绿光的短波长区域,这限制了CDs的广泛应用。多色CDs的合成对长波长CDs合成具有一定的指导作用,并且可以拓宽其应用。因此,本文从CDs的粒径、内部结构和表面态角度阐述了CDs的多色发光机理,综述了实现多色CDs的调控措施(包括反应原料、反应参数、表面改性和分离提纯)及其在发光二极管和生物成像方面的应用。Carbon dots(CDs) have attracted extensive attention of researchers because of their excellent fluorescence performance,low toxicity,extensive raw materials and good biocompatibility.However,the emission wavelengths of most CDs are in short-wavelength region of blue and green light,limiting their widespread application.The synthesis of multicolor CDs can guide the realization of long wavelength CDs and broaden the application of CDs.Therefore, the multicolor emitting mechanism of CDs from sizes,inner structures and surface states of CDs was reviewed,the adjusting measures of achieving multicolor CDs were presented,including raw materials,reaction conditions,surface modification,and separation and purification.Furthermore,the application of multicolor CDs in light emitting diode and bioimaging was also summarized.
