摘要: Reliable quantification of 3D results obtained by X-ray energy-dispersive spectroscopy (XEDS) tomography is currently hampered the presence shadowing effects and poor spatial resolution. Here, a method presented which overcomes these problems synergistically combining quantified XEDS data high angle annular dark field–scanning transmission electron microscopy tomography. As proof principle, approach applied to characterize complex Au/Ag nanorattle through galvanic replacement reaction. However, technique that proposed here widely applicable broad range nanostructures.
