First Electron Energy Loss Spectroscopy

Localised Surface Plasmon resonances in metallic nanoparticles are mapped by Electron Energy Loss Spectroscopy with both the spatial and spectral resolution. First results measured by Michal Horak in the CEITEC BUT Core Facility Structural Analysis Laboratory with FEI Titan Themis shows LSP resonance of gold disc nanoparticle on silicon nitride membrane. Observed LSP resonance at 1.35 eV has maximum in the middle of the nanoparticle and vanishes with increasing distance from the middle.
