On the localized surface plasmon resonance modes in nanoporous gold films

摘要

This work concentrates on the relation between plasmonic modes and the microstructure of nanoporous gold films. Based on experiments and computational analyses, we conclude that ligament as well as pore sizes need to be taken into account for an adequate physical description of the optical performance of a disordered nanoporous metal film as a function of its detailed microstructure.
