Description: 
The realization of periodic plasmonic nanostructures featuring macroscopic scale and easily controllable size and lattice spacing, is a challenging achievement for low-cost nanofabrication tools, which has not been completely explored so far. In this work, periodic array of different metal nanostructures have been easily prepared on large-area by exploiting a modified nano-sphere lithography (NSL) fabrication technique. A valuable ability is to couple the versatility offered by NSL with post-processing tools for a properly engineering of plasmonic nanoparticles. Obtaining dynamic tunability of metal nanostructures will allow the monitoring of electromagnetic near field distribution upon interaction with light of a desired wavelength. A rational design of such singular or collective optical properties can be used to focus and optimize the investigated functional features. Here, Au nano-prisms (NPs) and Au nanohole (NHs …
