Figure Lengend Snippet: Photophysical and (chiro)optical characterization of L/D-CDots. Experiments performed in water at 298 K. (A) UV–Vis spectra of L-CDots (black line) and D-CDots (red line). (B) FL emission spectra (at different excitation wavelengths) of L-CDots (same emission profiles and intensities were observed for D-CDots). (C) CD spectra of L-CDots (black line) and D-CDots (red line).

Article Snippet: UV-Vis absorption spectra were acquired on a Perkin-Elmer Lambda 750 UV-Vis spectrophotometer, and the slit width detail was 2.0 nm.
