(a) X-Ray Photoelectron Spectroscopy (XPS) full scan survey spectrum with (b) high-resolution C 1s spectra, (c) high resolution S 2p spectra and (d) high-resolution B 1s spectra of BS-GQDs. The black and red lines show the raw data and fitted curve respectively whereas other colored curves show specific bonds corresponding to spectrum of each element as shown in the label.
