Fig. 4From: Influence of Group Modification at the Edges of Carbon Quantum Dots on Fluorescent EmissionThe spectra of UV-Vis absorption by B- and N/S/P-CQDs in a. The PL spectra of b B-CQDs, c N-CQDs, d S-CQDs, and e P-CQDs with different excitation wavelengths as indicated. These results are obtained at room temperatureBack to article page
