Abstract.  We present a study of resonant optical properties of paired silver hemispheroids grown on a glass substrate using out-diffusion technique combined with thermal poling of the glass. Atomic force microscopy was used to characterize the morphology of the grown nanostructures. Dark-field spectroscopy and numerical simulation were applied to study the optical properties of the coupled nanoparticles (NPs) depending on the interparticle gap and size difference of the hemispheroids in a pair. Raman spectroscopy testing of the coupled hemispherical NPs showed that they can provide signal enhancement factor exceeding one of a single hemispherical NP.
