Preparation of Nitrogen-doped Fluorescent Carbon Dots and the Detection Performance for MnO4ˉ

摘要/Abstract

摘要：

以抗坏血酸和乙二胺为原料，采用一步水热法制备了氮掺杂荧光碳点(N-CDs).利用透射电子显微镜(TEM)、紫外-可见分光光度计(UV-vis)、傅里叶变换红外光谱(FTIR)和荧光光谱对N-CDs进行了表征，并研究了N-CDs对MnO4-的响应机制.结果表明，N-CDs平均粒径为6.41 nm，分散性良好、无明显团聚，荧光量子产率约为15 %.N-CDs对MnO4-有较高的选择性和灵敏度，其荧光猝灭程度与MnO4-摩尔浓度(0~60 μmol/L)之间呈良好的线性关系，对MnO4-的检出限为0.055 μmol/L，MnO4-对N-CDs的荧光猝灭机制为动态猝灭.N-CDs可用作荧光传感器，为水中MnO4-的检测提供一种灵敏的新方法.

Abstract：

Nitrogen-doped fluorescent carbon dots(N-CDs) were prepared by one-step hydrothermal method using ascorbic acid and ethylenediamine. N-CDs were characterized by transmission electron microscope(TEM), ultraviolent-visible spectroscopy(UV-vis),Fourier transform infrared(FTIR) and fluorescence spectrum.In addition，the response mechanism of N-CDs to MnO4- was investigated.The results showed that the average particle size of N-CDs was 6.41 nm,the dispersion was good with no obvious agglomeration,and the fluorescence quantum yield was about 15 %.Experiments indicated that N-CDs had the high selectivity and sensitivity to MnO4-,and the fluorescence quenching degree had a good linear relationship with the molar concentration(0~60 μmol/L) of MnO4-.The detection limit of N-CDs to MnO4- was 0.055 μmol/L,and the fluorescence quenching mechanism of MnO4- on N-CDs was dynamic quenching.N-CDs can be used as fluorescence sensor to provide a sensitive method for the detection of MnO4- in water.
