Probing the plasmonic response of an isolated Au nanorod using cathodoluminescence.

The spatial and spectral characteristics due to localized surface plasmon resonance of individual gold nanorod (NR) have been studied using cathodoluminescence (CL) in a high resolution scanning electron microscope (SEM). Simultaneous determination of morphology and luminescence with spatial resolution down to a few nanometers, from the same area of interest enables us to map different plasmonic modes supported by Au NR.
