首次以何首乌作为碳源水热法合成了荧光碳纳米点，我们考察了何首乌的用量、反应温度及反应时间对水热法合成过程的影响。实验结果表明，反应釜溶液总体积为30 mL的条件下，何首乌质量为0.5 g时得到的荧光碳点发光效率最高；同时，水热反应温度也不宜过高，反应温度为160℃，反应时间为3 h时得到的荧光碳点发光强度最高。

Fluorescent carbon nanodots utilized with Chinese herbs of polygonum multiflorum as a carbon source via hydrothermal method was developed for the first time.The effect of the amount of polygonum multiflorum , reaction time and temperature on hydrothermal synthesis process was investigated in the present work.Results showed that when the total volume of the solution was 30 mL, 0.5 g of polygonum multiflorum used was optimal because the obtained fluorescent carbon nanodots showed the highest luminescent efficiency.Besides , the optimized reaction time and temperature were set at 160 ℃and 3 h owing to fluorescent carbon nanodots with the highest fluorescent intensities.
