摘要：

In this work, we proposed a dielectric barrier discharge (DBD)-assisted one-pot strategy to fabricate carbon quantum dots (CQDs) using only one reagent N, N-dimethylformamide (DMF) at atmospheric pressure and room temperature. The experimental conditions were carefully investigated, and the prepared CQDs were characterized by using UV-vis spectrophotometer, fluorescence spectrophotometer, Fourier transform infrared (FTIR) spectrometer, transmission electron microscopy (TEM) and X-ray photoelectron spectrometer (XPS). The CQDs have an average size of 3.6 nm in diameter with narrow size distribution, and can be used as highly selective and sensitive fluorescence probes for hydrogen peroxide and glucose, with limits of detection of 3.8 mu M and 3.5 mu M, respectively.
