Paper Abstract

In the present work we investigated the properties and behavior of plasmonic modes of silver nanocube monolayers with respect to reflection and transmission of visible radiation. Uniform monolayers of low particle densities were created using the Langmuir-Blodgett technique using the phospholipid 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) as a passive spacer. Dipole-dipole coupling modes were avoided by depositing at low pressures to ensure sufficient spacing between the nanocubes. The refractive index sensitivities of plasmonic modes for monolayers on glass, silicon thin films, and bulk silicon wafers were measured using varying solutions of water and ethylene glycol. By varying the refractive index of the substrates it is possible to investigate the relative contribution of plasmonic modes with respect to absorption of the incident signal.
