摘要:

以丙三醇为原料, 经一步微波法制备了碳量子点(CDs). 所制备的碳量子点粒径分布在4~25 nm之间, 其平均粒径为16.5 nm. 荧光光谱结果表明, 相比于Cu2+, Ca2+, Mn2+, Co2+, Fe2+, Ni2+, Zn2+, Na+, Cd2+, Mg2+, Pb2+, K+和Ag+等13种常见金属离子, 该碳量子点对Fe3+显示出高选择识别性, 且Fe3+浓度在10~60 μmol/L之间呈现良好的线性关系, 检出限为2 μmol/L.

Abstract:

Glycerol was selected as sole starting material by one step microwave method for prepared a new type of carbon quantum dots(CDs). The size of th CDs distribute in 4—25 nm with the average particle size of 16.5 nm. In addition, the resulting CDs could exhibit a highly sensitive fluorescence response behavior to Fe3+ compared to other 13 kinds of metal ions including Cu2+, Ca2+, Zn2+, Co2+, Fe2+, Ni2+, Mn2+, Na+, Cd2+, Mg2+, Pb2+, K+ and Ag+. The detection limit of Fe3+ was calculated to be 2 μmol/L with a linear dynamic range of 10—60 μmol/L.

Key words: Microwave-assisted technique, Carbon quantum dots, Fluorescence spectrum, Fe3+
