Published Study Demonstrates New High-Resolution Imaging Capabilities of Energy-Filtered Transmission Electron Microscopy Using Gatan Imaging Filter (GIF®)

Researchers from the Institute for Electron Microscopy (FELMI) at the Graz University of Technology/ Austria and the SuperSTEM Laboratory, University of Glasgow reported on exciting new high-resolution utilities of energy-filtered transmission electron microscopy (EFTEM) using Gatan's post-column imaging filter (GIF^®). The report, entitled High-resolution surface plasmon imaging of gold nanoparticles by energy-filtered transmission electron microscopy, was published as a "Rapid Communication" in Physical Review B.*

Abstract: "We demonstrate the imaging capabilities of energy-filtered transmission electron microscopy at high-energy resolution in the low-energy-loss region, reporting the direct image of a surface plasmon of an elongated gold nanoparticle at energies around 1 eV. Using complimentary model calculations performed within the boundary element method approach we can assign the observed results to the plasmon eigenmodes of the metallic nanoparticle."*

Figure 1 from paper shown above. "FIG. 1. Color online a TEM bright field image of rod-shaped gold nanoparticle, with approximately 400 nm length and 75 nm diameter. The markers indicate pixel positions at which EELS spectra in Fig. 2 have been extracted. b – d EFTEM images at given energy-loss values. Image intensities have been normalized with respect to the maximum intensity of panel b. We use pseudocolor for better visibility. The EFTEM maps show the electromagnetic eigenmodes of the gold nanorod."
