Sulfur valence-to-core X-ray emission spectroscopy study of lithium sulfur batteries

Abstract

In this work the valence-to-core (VtC) Kβ sulfur X-ray emission spectroscopy (XES) was used to perform quantitative analysis of different sulfur compounds produced in the lithium sulfur (Li-S) battery during...

A parallel-beam wavelength-dispersive X-ray emission spectrometer for high energy resolution in-air micro-PIXE analysis

“…11 In our laboratory, a crystal spectrometer in Johansson geometry has been used for high energy resolution PIXE analysis with an energy resolution below the natural core-hole broadening, 12 and chemical speciation studies of low-Z elements in different materials have been performed. [13][14][15][16][17][18] Apart from their moderate efficiency, such spectrometers are also quite large, and require a complex alignment procedure and a xed beam spot, which is usually not compatible with ion microprobes. A compact at crystal WDS spectrometer coupled to an ion microprobe has been introduced recently, 19,20 mainly to perform chemical state analysis with focused ion beams and has not been used for PIXE mapping.…”

Resonant Excitation Unlocks Chemical Selectivity of Platinum Lβ Valence-to-Core X-ray Emission Spectra

“…For first row transition metals ,− and, increasingly, for other light atoms, − VtC XES has been established as a powerful, element selective tool capable of interrogating the geometric and electronic structures of an absorbing atom. For example, VtC XES of first row metal species can reveal the identity ,, and number of ligands bound to a metal center, their protonation state, and even the degree of intraligand bond activation .…”
