The antimonide oxides REZnSbO and REMnSbO (RE = Ce, Pr) – An XPS study

Synthesis and characterization of mixed conductor CeNbO4

“…2(d), three distinct regions of envelopes (around 880-890 eV, 895-910 eV, and 916 eV) can be seen in this spectrum. The complexity of the XPS spectra of the Ce3d is due to multielectric processes both in the Ce 4+ and Ce 3+ states and originates from the hybridization between the Ce4f levels and the O2p states [20,21]. The fitted peaks at 897.5 eV and 916 eV correspond to Ce (3d 9 4f 0 )O(2p 6 ) states of Ce 4+ and the peak 916 eV is normally taken as an indication to detect the presence of the Ce 4+ [22][23][24].…”

“…According to the literature [25,26], Ce 3+ oxide is characterized by two pairs of spin-orbit split doublet with two peaks. One doublet (884.8 and 903.7 eV) is characterized by the presence on Ce 3+ state and corresponds to the Ce (3d 9 4f 1 )O(2p 6 ) state [21]. The other doublet (881.4 eV and 899.4 eV) corresponds to Ce (3d 9 4f 2 )O(2p 5 ) state and is a shakedown feature involving electron transfer from a filled O2p orbital to a Ce 4f orbital during photoemission from Ce 3+ cations [23,27].…”

Nanostructured Antimony/carbon Composite Fibers as Anode Material for Lithium-ion Battery

“…In the Sb 3 d spectrum, two peaks at the binding energy of 530.8 eV and 540.3 eV are attributed to Sb 3 d 5/2 and Sb 3 d 3/2 (Fig. 4c), respectively [41,42]. Meanwhile, there is no peak observed at ca.…”

Structure of a Novel Spinel Li0.5Zn5/3Sb2.5/3O4 by Neutron and Synchrotron Diffraction Analysis

“…They have similar binding energies of 539.28 eV and 539.48 eV, respectively (Figure 5c). To circumvent the mentioned obstacle, the Sb concentration was determined via the Sb 3d3/2 peak (530.07 eV) [6,26,27]. The high-resolution spectra for Zn 2p, Sb 3d3/2, O 1s, and Li 1s are shown in Figure 5b-d.…”
