Silver nanocube monolayers deposited on polymer films were heated past the glass transition temperature of the polymer. Surface interactions between the cubes and substrate dictate the depth and rate of incorporation into the polymer. Silver nanocubes support hybrid plasmonic modes that are spatially separated when there is anisotropy in the local refractive index. Using this measure, it becomes possible...
Extinction spectra of nanocubes supported by a symmetry breaking dielectric substrate are very different from those in solution. In this work, we varied the refractive index of the substrate in order to optimize the refractive index sensitivity (RIS) of supported silver nanocube monolayers. We found that on thin (5–7 nm) silicon films, the RIS is characterized by the figure of merit (FOM) for the...
