Plasmon Resonances in V-Shaped Gold Nanostructures
Using numerical simulations, we examine the change in plasmon resonance behavior in gold nanorod structures that have a V shape. The reduction in symmetry compared to linear rods causes two different longitudi...

Thin Films of AuCuAl Shape Memory Alloy for Use in Plasmonic Nano-actuators
We describe the fabrication and structure of nanoscale thin films of β phase shape memory alloys with the nominal atomic stoichiometry Au7Cu5Al4 (corresponding to 5.8 wt% Al). These alloys possess properties that...

Spectrally selective coatings of gold nanorods on architectural glass
Infrared-blocking coatings on window glass can be produced by dispersing gold nanorods into a polymer coating. The spectral selectivity of the coating is controlled by the shape and aspect ratio of the nanopar...

A Computational Exploration of the Color Gamut of Nanoscale Hollow Scalene Ellipsoids of Ag and Au
Hollow, nanoscale, scalene ellipsoids of Ag or Au provide an exceedingly tunable localized surface plasmon resonance. Here, we use numerical simulations to determine the limits of the color space that would be...
