摘　　要：碳点(CDs)因其优异的水溶性、低毒性和环境友好性、强发光性、荧光颜色可调性、光稳定性和耐漂白性而引起广泛关注。炭化法、水(溶剂)热法和微波法具有工艺简单、原材料广泛、成本较低、制备的CDs荧光色丰富等优点,已成为制备方案的主流。综述了通过上述3种方法制备蓝、绿、红三基色CDs的最新研究进展;分析了通过不同方法制备的三基色CDs的属性;总结了影响CDs荧光呈色的主要因素,包括前驱体种类和浓度、反应溶剂的种类及反应温度等,指出当前在三基色CDs制备中面临的主要问题,提出了精确控制CDs发射波长为460、550和630 nm的潜在解决方案;从工业化应用和智能响应的角度,对三基色CDs加色法合成系列荧光色的未来发展方向进行了展望。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.
