Unveiling quasi-dark surface plasmon modes in Au nanoring cavities by cathodoluminescence
Abstract Spectral resolving and imaging surface plasmon modes in noble metal nanostructures are important for applications in nanophotonics. Here, we use cathodoluminescence (CL) spectroscopy to excite and probe quasi-dark plasmon modes of Au nanoring cavities. Numerical simulations of both the spec...
