| description | With the discovery of research, many properties of carbon dots are getting better and better. People have taken advantage of this and utilized them interspersed in various fields. In the present study, water-soluble nitrogen-doped carbon dots (N-CDs) with excellent optical and fluorescence thermal properties were prepared by the hydrothermal method using 4-dimethylaminopyridine and <i>N</i>,<i>N</i>′-methylenebisacrylamide as precursors. Co<sup>2+</sup> has a selective bursting effect on the fluorescence of N-CDs. The fluorescence of N-CDs is selectively burst by Co<sup>2+</sup>, and the high sensitivity is good in the range of 0–12 μM with a detection limit of 74 nM. In addition, the good temperature response (reversible and recoverable fluorescence in the temperature range of 20~90 °C) and excellent optical properties of the N-CDs also make them new potentials in the field of fluorescent inks and temperature sensing. |
