                 Abstract: Carbon dots (CDs) have attracted extensive attention because of their excellent water solubility,
                 low toxicity, environmental friendliness,  strong luminescence, tunable fluorescence,  photostability and
                 bleaching resistance.  Carbonization, hydrothermal (solvothermal) as well as microwave method, the
                 mainstream schemes for preparation  of CDs, exhibited advantages  of simple process, abundant raw
                 materials, low cost and rich fluorescent spectra. Herein, the latest progress in the preparation of blue, green
                 and red fluorescent CDs  by  the above-mentioned three  methods were reviewed  along with  the property
                 analyses. The main influence factors, such as type and concentration of precursor, type of reaction solvent
                 and reaction temperature, as well as the existing problems were discussed and summarized. Meanwhile, a
                 potential solution for accurate control of the emission wavelength at 460, 550 and 630 nm was put forward.
                 In the end, the future development direction was proposed from the perspective of industrial application and
                 intelligent response.
