摘　　要：本文以丙三醇和聚乙二醇-200为原料,微波法一步合成碳量子点(CDs),探究了CDs合成的微波功率、反应时间以及丙三醇/聚乙二醇-200的用料比例。结果表明,CDs的最佳合成条件为微波功率650W,反应时间150s,V(丙三醇)∶V(聚乙二醇-200)为3∶1。经荧光表征合成量子点,最大激发和发射波长分别在360nm、430nm,对发光分析有潜在的应用价值。Glycerol and polyethylene glycol-200 were used as raw materials to synthesize carbon quantum dots(CDs)in one-step by microwave method in this paper.The microwave power,reaction time and the volume ratio of glycerol to polyethylene glycol-200 for synthesis of carbon quantum dot were investigated.The results shown that the optimal synthesis conditions of carbon quantum dots were microwave power of 650W,reaction time of 150s,and the ratio of glycerol to polyethylene glycol-200 of 3∶1(v/v).The synthesized quantum dots were characterized by fluorescence,and the maximum excitation and emission wavelengths were 360 nm and 430 nm,respectively,which have potential application value for luminescence analysis.
