Abstract

Nitrogen and sulfur co-doped carbon dots (N, S-CDs) were prepared for dual-channel ratiometric fluorescence determination of mercury ions (Hg2+). The dual-emission N, S-CDs were synthesized using a simple one-pot hydrothermal treatment. When excited with visible light, N,S-CDs exhibited two emission peaks at 390 and 500 nm. Notably, the presence of Hg2+ caused a considerable decrease in the fluorescence of N, S-CDs at 500 nm, mainly due to the static quenching effect. In comparison, the fluorescence at 390 nm was almost unchanged. With a limit of detection (LOD) of 0.21 µM for Hg2+, the N, S-CDs were successfully applied to the unlabeled ratiometric fluorescence determination of Hg2+ in actual water samples with good recoveries (94.5-107.8%). In conclusion, this developed ratiometric fluorescent sensor provides a reliable, environmentally friendly, rapid, and efficient platform for detecting Hg2+ in environmental applications.

用于汞离子比率荧光测定的氮和硫掺杂碳点
制备了氮和硫共同掺杂的碳点(N, S-CDs),用于汞离子(Hg2+)的双通道比率荧光测定。这种双发射 N、S-CDs 是通过简单的一锅水热法合成的。在可见光的激发下,N,S-CDs 在 390 纳米和 500 纳米处显示出两个发射峰。值得注意的是,主要由于静态淬灭效应,Hg2+ 的存在导致 N,S-CDs 在 500 纳米波长处的荧光大大减弱。相比之下,390 纳米波长处的荧光几乎没有变化。Hg2+ 的检测限(LOD)为 0.21 µM,N, S-CDs 成功应用于实际水样中 Hg2+ 的非标记比率荧光测定,回收率良好(94.5-107.8%)。总之,所开发的比率荧光传感器为环境应用中检测 Hg2+ 提供了一个可靠、环保、快速和高效的平台。

期刊介绍: Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
