Lanthanum X-ray photoelectron spectra, lanthanum electron configuration, and other elemental information. 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.

XPS Signals for Lanthanum, (La o) Metal. Spin-Orbit Term, BE (eV) Value, and Scofield σ for Aluminum K α X-rays (1486 eV, 8.33 Ang)

XPS Spectra Lanthanum (La) Compounds 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. Atom% values are corrected for IMFP and PE.

2011年7月1日 · Angle resolved XPS (ARXPS), with its ability to discriminate between surface and bulk signal, would give useful contribution to the understanding of the sample surface composition. However, the inherent surface roughness of the powder samples inhibits meaningful ARXPS measurements [73].

2019年9月19日 · Lanthanum oxide (La 2 O 3) has attracted special attention as a promising catalyst for the oxidative coupling of methane (OCM) reaction. In this work, a new and reliable way of XPS calibration is developed by applying various in situ preparations for a nanorod La 2 O 3 catalyst to intentionally form different lanthanum compounds, followed by ...

Analysis of lanthanum by XPS is typically performed on the 3d orbitals, which may overlap with Fe 2s, In 3s as well as the KLL auger from flourine and the Ce LMM auger if using Al X-rays (1486.7 eV). Additionally, the La M 4,5 N 4,5 N 4,5 auger overlaps with the La 3d peaks when using Al X-rays which may complicate peak analysis (can be ...

In this manuscript, we report a novel photocatalysis of copper and lanthanum incorporating cerium oxide (CeO2) loaded on graphene oxide (Cu/La/CeO2/GO) nanocomposites suc-cessfully synthesized by...
