(a) Time-dependent absorption spectra of CNDs at a concentration of 300 mg ml−1 in a 1-mm quartz cell and (b) time-dependent mass-extinction coefficients of aqueous dispersions of CNDs with increasing concentrations measured at the absorption maxima of 593 nm for 10 mg ml−1, 605 nm for 50 mg ml−1, 630 nm for 100 mg ml−1 and 653 nm for 300 mg ml−1.
