XPS spectra and optical properties of h-GQDs and e-GOQDs.
XPS spectra for (a) h-GQDs and (b) e-GOQDs. PL spectra excited at different wavelengths for (c) h-GQDs and (d) e-GOQDs. PL emission spectra of (e) h-GQDs and (f) e-GOQDs. Insets of (e) and (f) are the digital images of h-GQDs and e-GOQDs under excitation 360 nm, respectively.
