本文以蛋氨酸为前驱体，采用水热法一步法制备了氮(N)和硫(S)共掺碳点。N和S掺杂量分别高达15.2at.%和19.5at.%。对光致发光数据的分析表明，激发光与相应的发射波长之间的关系可归结为线性拟合函数。此外，制备的NS-CDS对重金属离子也表现出灵敏的检测性能。由于这些优良的特性，NS-CDS在工业和环境监测中具有广泛的潜在应用前景。(C)2017爱思唯尔B.V.保留所有权利。
In this article, we prepare the nitrogen (N) and sulphur (S) co-doped carbon dots (NS-CDs) via a one-step hydrothermal method using the methionine as the precursor. The N and S doping content reach as high as 15.2 at.% and 19.5 at.%, separately. The analysis of the photoluminescence dates exhibits that the relationship between the excitation and the corresponding emission wavelength can be summarized as a linear fitting function. In addition, the as prepared NS-CDs also exhibits sensitive detection properties for heavy metal cations. With these excellent characteristics, there are extensive potential applications for NS-CDs in industry and environmental monitoring. (C) 2017 Elsevier B.V. All rights reserved.
