Description
We study plasmon assisted luminescence from an isolated single trisoctahedral (TOH) gold (Au) nanocrystal using cathodoluminescence (CL) spectroscopy and imaging in a field emission scanning electron microscope (FESEM). The site specific e-beam excitation reveals a double peaked spectrum with the localized surface plasmon resonance (LSPR) at 540 nm and 660 nm and a single resonant peaked spectrum at 560 nm. The spatial variation of the plasmon assisted luminescence was strongest at the apex points as well as at the edges and corners.
