A Fluorescent Nanosensor for Silver (Ag<sup>+</sup>) and Mercury (Hg<sup>2+</sup>) Ions Using Eu (III)-Doped Carbon Dots

Carbon dots doped with Eu<sup>3+</sup> ions (Eu-Cdots) were prepared by a hydrothermal treatment, using citric acid and urea as precursors and Eu (NO<sub>3</sub>)<sub>3</sub> as a europium source. The Eu<sup>3+</sup> ions are strongly coordinated with the carboxylate groups at the surface of the Cdo...
