WebDec 1, 2024 · The insightful chemical and structural information of c-BiOCl was examined at atomic level by a series of techniques like synchrotron XAS, XPS and Raman spectra. The Bi L3 -edge normalized X-ray absorption near-edge structure (XANES) spectrum of c -BiOCl is similar to that of o -BiOCl ( Fig. 2 a). WebMay 2, 1995 · XAFS spectra were recorded on transmission mode using a Si (111) monochromator crystal. X-ray absorption spectra at the bismuth Lilt-edge were reduced to normalized XAFS X (k) using Daresbury software and weighted k3X (k) data analyzed using the EXCURV suite of program [14,15).

WebJan 9, 2024 · 5: Magnetic Resonance Spectroscopies X-ray absorption fine structure (XAFS) spectroscopy is one of the most powerful tools we have for mapping local structure. In this technique, we probe a sample with x-rays that are tuned to the energy of a core electron shell in the element we wish to study. WebApr 18, 2024 · Fe K-edge XAFS also indicated that there was a competition between hybridization of Fe 3d and Al 3d with O 2p orbitals and occurrence of the more 4p orbitals with Al doping. The Bi L3-edge XAFS revealed that transition from 2p3/2 to 6d state increased, so did the energy of 6d state. ... Chemical reagents used in this work were …
