Manipulation of light on the nanoscale, as well as the control of light-matter interactions are desirable for a manifold of applications, including high sensitivity imaging and sensing applications, solar cells and novel optical devices. Here we report on the Purcell effect in a close-packed self-assembled monolayer of dye-doped dielectric nanospheres coated with a silver film. The comparison between...
The race toward engineering metamaterials comprising of negative refractive indexes in the optical range started with the realization of negative-index materials for gigahertz frequencies six years ago. Sheer miniaturization of the gigahertz resonant structures is one approach. Alternative designs make use of localized plasmon resonant metal nanoparticles or nanoholes in metal films. Following this...
