Development and Application of Laboratory X-ray Fluorescence Holography Equipment
The X-ray fluorescence holography (XFH) method has drawn the attention of many researchers as a novel experimental technique for imaging a three-dimensional local atomic structure around a certain element in a single crystal. Synchrotron radiation (SR) has been mainly used for the measurements because of extremely weak signals which are about 0.3 % of isotropic fluorescent radiation. The measur...
متن کاملRapid Acquisition Pair Distribution Function (RA-PDF) Analysis
An image plate (IP) detector coupled with high energy synchrotron radiation was used for atomic pair distribution function (PDF) analysis, with high probed momentum transfer Qmax ≤ 28.5 Å−1 from crystalline materials. Materials with different structural complexities were measured to test the validity of the quantitative data analysis. Experimental results are presented here for crystalline Ni, ...
متن کاملAtomic-scale structure of nanocrystalline CeO2–ZrO2 oxides by total x-ray diffraction and pair distribution function analysis
Total x-ray diffraction and atomic pair distribution function analysis have been used to determine the atomic ordering in nanocrystalline (∼1.5 nm in size) CeO2–ZrO2 prepared by a sol–gel route. Experimental data show that the oxides are a structurally and chemically inhomogeneous mixture of nanoscale domains with cubic-type and monoclinic-type atomic ordering, predominantly occupied by Ce and ...
