La3d is the primary XPS region, but La4p and La4d regions can help assign the chemistry of lanthanum compounds. La3d region has well-separated spin-orbit components. Each spin-orbit component is further split by multiplet splitting.

The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections.

The XPS spectra of La (3d) core level for 9LZO are deconvoluted into two peaks located at the B.E. of 836.6 and 853.3 eV, corresponding to La 3+ (3d 5/2 ) and La 3+ (3d 3/2 ), respectively...

Sep 5, 2014 · The electronic structure of the polycrystalline La 0.67 Ca 0.33 Mn 1−x Co x O 3 compounds with x = 0.5, 0.6, 0.7, 0.8, 0.9 and 1 has been investigated by X-ray photoelectron spectroscopy (XPS). The valence band and the transition metal core level spectra were analyzed.

On the other hand, the XPS spectra of La-3d (figure 11 (a)) provides the evidence for trivalent electronic state corresponding to the 3d 5/2 (P La1 of BE ∼ 834.69 eV) and 3d 3/2 (P La2 of...

Jul 1, 2011 · A technique is described for deposition of gold nanoparticles under vacuum, enabling consistent energy referencing of X-ray photoelectron spectra obtained from lanthanum hydroxide La (OH) 3 and in situ treated lanthanum oxide La 2 O 3 powders.

Figure 3d demonstrated the core level spectra of La3d. The peaks associated to 850.8 and 855.5 eV attributed to binding energy values of La3d 3/2 , whereas peaks at 834.4 and 838.4 eV were for...

May 1, 2019 · Herein, a methodology to study the content of nickel and lanthanum by X-Ray photoelectron spectroscopy - XPS in FCC catalyst was developed. A critical problem to study the nickel in this type of material is related to the overlapping between Ni …

By employing x-ray photoelectron spectroscopy, we present a detailed study of the core level spectra of LaTe3 in its charge density wave phase at room temperature.

Sep 23, 2016 · The XPS spectra (Fig. 11.4) are referred to the internal levels of La3d, Co2p, and O1s. The LaCoO 3 displays one peak for Co 2p 3/2 centered at 781.39 eV, which is assigned to Co 3+.
