EPR spectra of CQDs (25 μg mL−1) in a DMSO and b aqueous solutions at 0 min, 10 min, 20 min and 30 min. Different time points reveal the variation in relaxation rates of magnetic edge state electrons. c Absorption spectra of CQDs in DMSO. d Absorption spectra of CQDs and ox-CQDs (25 μg mL−1) in aqueous solution. inset: IR thermal images of CQDs and ox-CQDs (1 mL, 250 μg mL−1) at different time points under 1064 nm laser irradiation (1 W cm−2). e Simulation structure of the CQDs and equatorial layers. a.u., arbitrary units. Source data are provided as a Source Data file.
