Figure 2

Photoluminescence excitation-emission-intensity spectra of C-dots dispersed in different solvents: (a) water, (b) ethanol, (c) hexanol. The intensity is shown in a false color scale. The spectrum region with an emission intensity higher than 25% of C-dots in water is shown as reference (white dotted line). (d) Excitation spectra of C-dots in water corresponding to the emission at 430 nm (black line, top) and at 490 nm (red line, bottom). The latter curve is formed by two overlapped components (blue and green lines) that have been separated by deconvolution.
