Jan 2, 2025 · Survey and high-resolution (Mg 1s, Mg 2p, S 2p) x-ray photoelectron spectra of as-received magnesium sulfide powder (99.9%) are presented, including surface contaminants that originate from exposure to atmosphere (C 1s, O 1s).

Jun 2, 1993 · The structure of MgKa X-rays, for application to XPS, has been re-examined for the Kal, Ka2, Ka', Ka3, Ka3, Ka4, Kas and Kab components. 1. Introduction Most X-ray photoelectron spectroscopy is still performed with achromatic X-ray sources, most commonly producing Mg and/or AlKa radiation.

Nov 10, 2006 · The distributions of unoccupied electronic states in the conduction bands of MgS and CaS have been determined. It has been found that the bottom of the conduction band of MgS is formed by Mg s and S s states, and of CaS by S d, s and p states.

Dec 20, 2007 · A detailed investigation of the initial film grown on mechanically polished Mg electrodes has been carried out by ex situ X-ray Photoelectron Spectroscopy (XPS) and in situ Photocurrent Spectroscopy (PCS), allowing to reach a detailed picture of …

Nov 10, 2006 · The KMM radiative Auger (RA) x-ray spectra of solid Ca were induced by monochromatic synchrotron radiation and measured with a high-resolution von Hamos bent crystal spectrometer.

Jun 1, 2021 · Ag + ions incorporated MgS nanoparticles were synthesized by the co-precipitation method. X-ray diffraction (XRD) spectra revealed that the samples had a cubic structure and the transmission electron microscope (TEM) pictures confirmed the spherical shape and size of the particle. The particle size was ranged from 11 nm to 15 nm.

Apr 19, 2004 · It was shown that in the Mg 1 − x Fe x S solid solution, iron sulfide changes its structure from NiAs-type (B 8) to NaCl-type (B 1) under the influence of the MgS matrix. The partial electronic densities of unoccupied states have been calculated for MgS and CaS.

The powder X-ray diffraction (XRD) pattern of the Fe3O4 NPs was obtained using a Siemens D5000 diffractometer (Aubrey, TX, USA) and an X-ray generator (CuKα radiation with λ = 1.5406 Å) at...

Jan 10, 2023 · Recently, Chen et al.11 reported quantitative XPS studies of oxide film growth on Mg and Al surfaces using XPS, where they estimat-ed film thickness from the intensity ratio of the oxidic to metallic components because the substrate is a single element.

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.
