Abstract
We report for the first time that the red fluorescence of leaf-derived carbon dots is derived from chlorophyll, and a possible formation structure is proposed. By controlling the solvothermal reaction temperature, the new luminescence center of CDs can be adjusted. This work provides unprecedented insights into the luminescence mechanism of biomass-derived CDs.
