Interactions Of Organic Fluorophores With Plasmonic Surface Lattice Resonances, Robert J. Collison
Interactions Of Organic Fluorophores With Plasmonic Surface Lattice Resonances, Robert J. Collison
Dissertations, Theses, and Capstone Projects
It is common knowledge that metals, alloys and pure elements alike, are lustrous and reflective, the more so when a metal surface is flat, polished, and free from oxidation and surface fouling. However, some metals reflect visible light, in the 380 nm to 740 nm range of wavelengths, much more strongly than others. In particular, some metals reflect wavelengths in certain portions of the ultraviolet (UV), visible, and near-infrared (NIR) regime, let us say 200 nm to 2000 nm, while absorbing light strongly in other segments of this range. There are several factors that account for this difference between various …
Control Of Light-Matter Interactions Via Nanostructured Photonic Materials, Nicholas Proscia
Control Of Light-Matter Interactions Via Nanostructured Photonic Materials, Nicholas Proscia

The thesis here investigates the manipulation of light-matter interactions via nanoscale engineering of material systems. When material systems are structured on the nanoscale, their optical responses can be dramatically altered. In this thesis, this is done in two primary ways: One method is by changing the geometry of nanostructures to induce a resonant behavior with incident electromagnetic field of optical wavelengths. This allows field enhancement in highly localized areas to strengthen exotic light-matter interactions that would otherwise be too weak to measure or for practical use. In this regard, the work presented here studies a voltage produced in a metal …
