X-ray photoelectron spectroscopy (XPS or ESCA) curve fitting procedures, reference materials and useful notes are listed here to provide a starting point for the consistent interpretation of XPS spectra.

photoelectron spectroscopy (XPS), powder X-ray diffraction (XRD), infrared spectroscopy and high-resolution solid-state 31P NMR spectroscopy. A progressive polymerization from orthophosphate to metaphosphates is observed by XRD, ATR-FTIR and solid state 31P NMR, and on this basis the oxygen

Phosphorus X-ray photoelectron spectra, phosphorus electron configuration, and other elemental information. P2p peak has closely-spaced spin-orbit components (Δ=0.87eV). Effect of spin-orbit splitting can be observed for phosphorus elements and compounds.

Feb 15, 2023 · During the process of expanding the content of Al(PO 3) 3, deconvolution of O 1s and F 1s in XPS spectrum revealed that the increase of P O and F P bond content resulted in the structural distortion of polyhedral P[O, F] 4 in glass structure and enhanced the disorder of glass.

Jan 1, 1998 · Monochromatic radiation provides a distinct clarity to the rich peak structure in the valence band of aluminum metaphosphate due to the absence of interfering x-ray satellites from the intense O 2s region. The valence band, survey, and the Al 2s, Al 2p, O 1s, and C 1s core levels are reported.

From the X-ray photoelectron spectroscopy (XPS) analysis of Pt/Al(PO 3) 3, the supported Pt nanoparticles contain both Pt 2+ (72.5 and 76.0 eV) and Pt 0 (71.6 and 74.7 eV) species (Figure 3d).

The XPS spectrum of CH-900 (Fig. 4a) shows two peaks at 283.8 and 534.6 eV, corresponding to C 1 s and O 1 s, respectively, where the content of C element is much higher than that of O element ...

The electrochemical analyses reveal NaCo(PO3)3 to be an active sodium insertion material with well-defined reversible Co3+/Co2+ redox activity centered at 3.3 V (vs Na/Na+).

Jul 8, 2020 · X-ray photoelectron spectroscopy (XPS) is widely used to identify chemical species at a surface through the observation of peak positions and peak shapes. It is

X-ray photoelectron (XPS) and X-ray Auger electron spectroscopy (XAES) were used for investigating the chemical and structural states of various aluminates. A clear chemical shift in Al modified Auger parameter (AP) for coordination state of Al atom was observed.
