(a) Schematic sketch of a double-resonant hybrid plasmonic/dielectric nanoantenna system together with the coordinate system used in this work. (b)–(f) Top-view SEM micrographs of the investigated ZnS nanostructures, bare gold nanoantennas, nanoantennas with ZnS nanoparticles, nanoantennas with LaF3 nanoparticles, and double-resonant nanoantenna systems with ZnS nanoparticles.
