In-situ XAFS measurements of amorphous Li3PO4-doped V2O5 cathode for all-solid-state thin-film Li-ion batteries

Scientific Reports
In this study, in-situ X-ray absorption fine structure (XAFS) measurements were conducted on amorphous Li3PO4-doped V2O5 (VO-LPO) cathode in an all-solid-state thin-film lithium-ion battery to observe the behavior of Li ions during charge/discharge.

Theory of photon interference X-ray absorption fine structure

Journal of Synchrotron Radiation, 2001
The theory of photon interference X-ray absorption fine structure (πXAFS) is described. Due to coherent X-ray scattering from atoms, a spatial variation of the X-ray intensity is produced inside the sample. The intensity at the X-ray absorbing atom changes according to the incident energy. Thus πXAFS in extended absorption spectra is produced.

Solving self-absorption in fluorescence

IUCrJ, 2019
One of the most common types of experiment in X-ray absorption spectroscopy (XAS) measures the secondary inelastically scattered fluorescence photon. This widespread approach has a dominant systematic of self-absorption of the fluorescence photon.
