Imaging of plasmonic modes of silver nanoparticles using high-resolution cathodoluminescence spectroscopy
Pratik Chaturvedi, Keng Hsu, Anil Kumar +2
Cathodoluminescence spectroscopy has been performed on silver nanoparticles in a scanning electron microscopy setup. Peaks appearing in the visible range for particles fabricated o…
