Elimination of self-absorption in fluorescence hard-x-ray absorption spectra

摘要: Fluorescence detection is a convenient way to measure x-ray absorption spectra in situations where samples cannot be made the required configuration. However, self-absorption effects cause considerable distortion of measured fluorescence. We describe straightforward procedure correct for such hard-x-ray region using known energy dependence coefficients. This used obtain vanadium K-edge spectrum single crystal ${\mathrm{V}}_{2}{\mathrm{O}}_{3}$ and we demonstrate that properly corrected. facilitates use fluorescence even region.
