Oxygen X-ray photoelectron spectra, oxygen electron configuration, and other elemental information. Charge referenced to adventitious C1s peak at 284.8eV. The O1s region may be overlapped by peaks from antimony, palladium, or vanadium.

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.

2023年7月3日 · This work will rectify many misinterpretations of XPS data of the O 1s region in metal oxides, provide guidance for precisely understanding the oxygen states of a material, and subsequently enable the real origin of material properties to be revealed.

2021年10月1日 · In recent years there has been a large number of articles wrongly attributing, an XPS O1s signal at about 531–532 eV to oxygen vacancies. These studies are based on ex situ measurements of powder materials.

Gaussian XPS peak fitting was used to deconvolute the broad spectrum of O 1s at 531.8 eV, which produced two distinct peaks at 531.1 and 532.8 eV which are ascribed to the M − O and M − OH ...

Common oxygen, O(1s) binding energies: Many (pure) oxide samples exhibit a secondary structure to higher binding energy of the main lattice oxygen peak. Careful consideration of the sample history can aid in the identification of this peak.

2024年11月1日 · In this study, a set of commercially available IrO x materials is used as a support to establish a peak-fitting model for oxygen 1s spectra and define an accessible descriptor of the oxide surface to go beyond the amorphous/rutile qualification.

The deconvoluted O 1 s spectra in Fig. 5d shows peaks centred at 529.2 eV, 530.5 eV and 529.2 eV which correspond to lattice oxygen species (O L ), oxygen defects in lattice (O V ) and...

Recent technical advances in X-ray photoelectron spectroscopy (XPS) have largely overcome differential charging of insulator surfaces, with the result that O 1s linewidths for silicates can be routinely collected that are 50% to 100% narrower than had been previously obtainable.

The lattice oxygen of metal oxides typically gives a strong XPS signal at 530 eV, being the binding energy of the O 1s electrons. For almost fifty years a weaker peak at 531 eV has been interpreted as being from "oxygen deficient regions", a.k.a. lattice …
