The XPS
spectra show the peaks relating to Ag and Cl. The peaks centered
at 366.8 and 372.7 eV correspond to Ag 3d5/2 and Ag 3d3/2, while
the peaks at 197.1 and 198.7 eV are consistent with the peaks of
Cl 2p1 and 2p3. The Ag 3d peaks could be divided into different
peaks located at 367.9 and 374.1 eV, which could be ascribed to
