摘要：

A facile and eco-friendly approach for synthesizing fluorescent tungsten disulfide (WS2) nanosheets was developed via nitrogen atom doping using melamine as the nitrogen source. After nitrogen atom doping, the WS2 showed excellent ultraviolet emission and good stability. Further, the fluorescent WS2 was used as a fluorescent probe for mercury(ii) (Hg2+) detection, with a detection limit of 0.02 M. Finally, this fluorescent nanoprobe was applied to the determination of Hg2+ in real water samples and demonstrated satisfactory results.
