Jan 15, 2012 · In this work we report a core level XPS study of K 2 O–SiO 2 glasses, emphasizing the O 1s, Si 2p and K 2p spectral lines. The XPS data provide evidence for two types of BO atoms and the presence of O 2−; an oxygen atom not bonded to a silicon atom.

XPS measures the kinetic energy of the photoelectrons emitted from a sample exposed to monochromatic X-rays. The energies of the emitted electrons are characteristic of the elements present and also the chemical bonding or oxidation state of the elements.

N*number) identifies the number of NIST BEs that were averaged to produce the BE in the middle column. Binding Energy Scale Calibration expects Cu (2p 3/2) BE = 932.62 eV and Au (4f 7/2) BE = 83.98 eV. BE (eV) Uncertainty Range: +/- 0.2 eV Charge Referencing of insulators is defined such that the Adventitious Hydrocarbon C (1s) BE (eV) = 285.0 eV.

Feb 1, 1996 · The surface properties of Mo oxides (MoO 2 and MoO 3) were investigated using X-ray photoelectron spectroscopy (XPS). As-prepared MoO 3 showed two well resolved spectral lines at 232.5 and 235.6 eV, which were assigned to …

The Thermo Scientific K-Alpha X-ray Photoelectron Spectrometer (XPS) System brings a new approach to surface analysis. Focused on delivering high-quality results using a streamlined workflow, the K-Alpha XPS System makes XPS operation simple and intuitive, with no sacrifice in terms of performance or capabilities.

As shown in the XPS of Mn 2p and W 4f in Figure S5, after K + loading, the Mn 2p core-level binding energy shifts up, indicating an electron transfer from Mn to K.

Imaging and mapping with X-ray photoelectron spectroscopy. While used to identify points or small features at the surface, XPS can also be used to image the surface of a sample.
