Simultaneous measurements of small-angle X-ray diffraction, wide-angle X-ray diffraction and X-ray emission spectra of Au NPs. (a) Small-angle diffraction pattern of a single Au NP. (b) Au (111) and (200) Bragg peaks from the same particle measured in (a). (c) Intensity profiles of two peaks displayed by averaging the diffraction ring azimuthally. They were normalized with the maximum intensity. (d) Accumulated Lα1 (9.713 keV) and Lα2 (9.628 keV) emission lines of the Au NPs acquired using a von Hamos spectrometer. (e) Intensity profiles of two emission lines. More than 1000 X-ray pulses were accumulated to improve the SNR of the emission lines. |
