“…S2 †), which means that short wavelength light is absorbed and converted into longer wavelength emission. 2,10,49 As the concentration of CNDs in the solution increases, the maximum emission redshis to longer wavelength (Fig. 2b and c) and the corresponding optimal excitation wavelength also redshis (Fig.…”

“…This may be caused by aggregation of CNDs at higher concentrations, leading to enhanced p-p* transitions of C]C bonds and n-p* transitions of C]O/C]N bonds. 10,49 The uorescence emission of aqueous solutions of CNDs is excitation wavelength-dependent (Fig. S2 †), which means that short wavelength light is absorbed and converted into longer wavelength emission.…”

“…46 The existence of these functional groups leads to a diversity of the surface states of CQDs, which enhances their UV radiation absorption capacity. 47 Additionally, there is no noticeable difference in the position and intensity of the FT-IR peaks of CQDs before and after aging, suggesting the superior structural stability of CQD powder. XPS measurement (Figure 2e,f) is helpful to detect the surface composition of CQDs; the C 1s band shows three distinct peaks at around 284.8, 286.2, and 288.2 eV, assigned to C−C/C�C, C−N/C−O, and C�N/C�O, respectively.…”
