High-resolution chemical imaging of gold nanoparticles using hard x-ray ptychography

(author unknown)



R. Hoppe, J. Reinhardt, and G. Hofmann et al.

We combine resonant scattering with (ptychographic) scanning coherent diffraction microscopy to determine the chemical state of gold nanoparticles with high spatial resolution. Ptychographic images of the sample are recorded for a series of energies around the gold L3 absorption edge. From these d ... [Appl. Phys. Lett. 102, 203104 (2013)] published Mon May 20, 2013.
