Quantitative Fluorescence EXAFS Analysis of Concentrated Samples–Correction of the Self-Absorption Effect

The EXAFS amplitudes of concentrated samples measured in the fluorescence mode strongly depend on the detection geometry through the self-absorption effect. Knowing the stoichiometry of the sample, we can fully correct for the self-absorption effect using a simple theory and obtain the true EXAFS. T...

Summary:The EXAFS amplitudes of concentrated samples measured in the fluorescence mode strongly depend on the detection geometry through the self-absorption effect. Knowing the stoichiometry of the sample, we can fully correct for the self-absorption effect using a simple theory and obtain the true EXAFS. The correction procedure presented here for the Oxygen K-edge EXAFS of NiO is generally applicable and should be the first step in the quantitative analysis of fluorescence EXAFS data of concentrated samples.
