摘要: Currently, the excitation-wavelength-dependent photoluminescence of traditional carbon dots does not constitute true tuning and their absorptions show gradual attenuation in the visible region. Herein, we report a facile strategy to realize intense visible absorption and full-color emissions of nitrogen doped carbon dots via the control of surface nitriding. The quantum yields of the carbon dots in aqueous solution reached 49.2%, 30.6% and 30.3% for blue, yellow and red emissions, respectively. Structural characterizations and spectroscopic …
