Xps Spectra Of The Bi2o3 Rgo A Survey Spectrum B Bi Download scientific diagram | xps spectra of the bi2o3 rgo: a survey spectrum, b bi 4f, c c 1s, and d o 1s from publication: a novel ultrathin single crystalline bi2o3 nanosheet wrapped by reduced. The survey spectrum (fig. 3 a) shows the presence of the elements bi 4f, o 1 s, b 1 s, and c 1 s. bi 4f 7 2 and bi 4f 5 2 are indexed to peaks at 159.1 and 164.5 ev, respectively ( fig. 3 b). the valence state of bi 3 in the composite is revealed by the 5.4 ev gap between bi 4f 7 2 and bi 4f 5 2 .

Xps Spectra Of The Bi2o3 Rgo A Survey Spectrum B Bi The chemical states and composition of bi 2 o 3 @rgo were characterized by using xps. figure 4a displays the xps survey spectrum, which shows the presence of elements bi, o, and c. the bi 4f 7 2 and bi 4f 5 2 peaks of bare bi 2 o 3 and bi 2 o 3 @rgo composite are presented in fig. 4b. The complete xps survey scan revealed that the existence of only bi, o, and c elements exemplifies that the sample was in a pure state (fig. 4 a). for the bi 4f elemental scan (fig. 4 b), the peaks observed at 164.2 and 158.8 ev, ascertained to the bi 4f 5 2 and bi 4f 7 2 spins of the bi 3 moieties [31]. download: download high res image (537kb).

Xps test is further carried out to analyse the chemical compositions and detailed surface electronic states. the survey spectrum displays that the existence of bi, c and o elements in as prepared materials (fig. 1c), which are in good match with the eds results. as shown in fig. 1d, the spin splitting of bi 4f peaks consists of bi 4f 7 2 and bi 4f.
