We report on confocal microscopy imaging of hybrid nanostructures composed of silver nanowires and corroles. Both nanomaterials were separated by a 30 nm thick SiO_2 spacer in order to inhibit fluorescence quenching. The results show that for such a hybrid nanostructure the average enhancement of the fluorescence intensity reached 2.5. Importantly, the coupling to plasmon excitations in metallic nanowires...
In this work we consider the tuning of spectral reflectance of fishnet metamaterials with circular or elliptic apertures due to the presence of dielectric analyte adsorbed within the pores of the dielectric part. We simulated the electromagnetic response of the fishnet metamaterials for the optical range utilizing the finite element method. Our investigation is dedicated to ultrathin, freestanding...
