The functional group and morphology of CNPs were characterized by Fourier Transform-Infrared Spectroscopy (FT-IR) and Transmission Electron Microscopy (TEM), respectively. Water-soluble CNPs exhibited an excellent blue fluorescence which can be applied for cerium (Ce3+) detection. In addition to taking advantage of high fluorescent Ce3+-CNPs, the corresponding reaction for detecting active hydroxyl radical was studied through the scavenging activity by turning off of emission.ChemistryArticleSCOPUS10.1016/j.diamond.2023.1103492-s2.0-85171623380
