Xps Spectra Of A Pd3d B Ag3d C Pt4f And D Au4f Of Noble Metal Xps spectra obtained for the pt ag nanopar ticles are presented in fig. 4c (ag3d core region) and 3d (pt 4f core region). the binding energy of ag3d 5 2 at 368.56 ev (peak a) is close to that of. Fig. 2 shows high resolution xps core level spectra of the metallic copper (upper row), cu 2 o (middle row) and cuo (bottom row) reference samples. the high resolution cu 2p spectrum of metallic copper in fig. 2 a can be deconvoluted into two sharp peaks at binding energies (be) of 932.6 ev and 952.4 ev, which are assigned to the cu 2p 3 2 cu 2p 1 2 doublet, respectively.
Xps Spectra Of The Pt 4f And S 2p Core Level Peaks Of The Films The area ratio for the two spin orbit peaks (2 p 1 2:2p 3 2) will be 1:2 (corresponding to 2 electrons in the 2 p 1 2 level and 4 electrons in the 2 p 3 2 level). these ratios must be taken into account when analyzing spectra of the p, d and f core levels. an example of this splitting for the sc 2 p peak for sc 2 o 3 is shown in figure 1. The other factor increasing the asymmetric tail of pt4f peak is specific for nanoparticles supported on ar sputtered hopg surface and involves the presence of small pt nanoclusters attached to defect carbon sites which appear at higher binding energy in the photoelectron spectra (the core level is 72.9 ev for atomic pt and 72.3 ev for pt 10.

The energy of c1s at 285 ev was taken as reference for the calculation of core level binding energies. the nitrogen of pvp was visible in all cases in the general spectra, proving that the metal nanoparticles are embedded by pvp. fig. 3 displays the data from cu2p 3 2, pt4f, and ag3d core level regions of the analyzed samples. Figure 13a shows the deconvoluted xps spectrum of pt 4f, where the observed peaks at around ~ 70.8 ev and ~ 74.1 ev correspond to the pt 4f 7 2 and pt 4f5 2 core level spectra of pt element.
