Fig. 16 Schematic diagram of an X-ray photoelectron spectrometer (Lee and Flynn 2006)
Fig. 17 XPS spectra of pure ZnO and Ag doped ZnO nanostructures (Patil et al. 2015)
for ZnO and Ag-ZnO samples display doublets peaks at 1044.3 and 1021.1 eV which
is ascribed to the Zn 2p5/2 and Zn 2p3/2 lines, respectively (Fig. 17a). The difference
between two bonding energies implies that Zn is in a +2 oxidation state. The O 1s
spectra of ZnO and Ag-ZnO samples with a peak at a binding energy of 529.75 eV
are shown in Fig. 17b. Figure 17c displays a peak at 285 eV for the C 1s spectra of
