Optical Characteristics of Nano Space of Silver Nanowire on a Silver Mirror

Abstract

Localized surface plasmons in sub-nanometer gaps defined by metal nanoparticle dimer has recently attracted attention as a high-sensitivity sensor with a small volume. We demonstrated multiple gap plasmons by a single silver nanowire with a spacer layer on silver film i.e., nanowire on mirror (NWoM) in the dark-field with polarization-dependent.
