Strong location dependent surface enhanced Raman scattering on individual gold semishell and nanobowl particles.
We demonstrate strong spatial localization of SERS on single symmetry-reduced gold semishell and nanobowl particles. A ∼30 nm carbon nanoparticle acts as a Raman reporter and is placed on different locations on a single semishell or nanobowl by e-beam induced deposition method, and remarkably different SERS intensities are observed.
