Plasmonic Filters Based on Lithographically Patterned and Hexagonally Arranged Triangular Silver Nanoparticles Array

Figure 8

Schematic illustration of silver nanoparticle array fabrication with the following two steps: (1) drop-coating of monolayered PS nanospheres on substrate; (2) deposition of a layer of silver film over the as-coated monolayered PS nanospheres.
