SiO(2) and TiO(2) dielectric nanoparticles are arranged in linear arrays, supporting collective modes, and employed as dielectric nanoantennae. Electrodynamic calculations show that strong, tunable lossless light extraction is obtained in a wide spectral range, including UV, visible, and near-infrared regions, III opposition to poor enhancement features of isolated dielectric nanoparticles. Emission quantum efficiencies comparable to those obtained employing metallic structures are achieved, with strong emission enhancement even for poor emitter position and dipole moment orientation.

Abstract
SiO(2) and TiO(2) dielectric nanoparticles are arranged in linear arrays, supporting collective modes, and employed as dielectric nanoantennae. Electrodynamic calculations show that strong, tunable lossless light extraction is obtained in a wide spectral range, including UV, visible, and near-infrared regions, III opposition to poor enhancement features of isolated dielectric nanoparticles. Emission quantum efficiencies comparable to those obtained employing metallic structures are achieved, with strong emission enhancement even for poor emitter position and dipole moment orientation.File in questo prodotto:
