Paper Abstract
UV plasmonic nanostructures have applications in label free native fluorescence biosensing. Many aluminum
nanostructures have been shown to modify emission properties of UV fluorescence molecules. However, these structures
demonstrate small rate enhancement factors (less than 10x). In this paper, we report FDTD simulation results on
excitation and emission enhancement factors of a pair of aluminum bowtie antenna in ultraviolet region. Our results
show that the optimal geometry is a pair of small bowtie (radius 20nm) with apex angle 60 degrees. The highest radiative
enhancement is 25x (~340nm) and highest total decay rate enhancement is 70x, higher than previously studied
geometries.
