Surface Plasmon Polariton Dependence on Metal Surface Nano-Structure


EMSL Project ID
24395

Abstract

The project will focus initially on films of nano-structured gold metal particles. A motivation for this is that so-called nano-structured "gold black" is currently under investigation at UCF as an absorptive coating for novel MEMS-based room temperature bolometers for defense & security applications. Such materials display strong absorption resonances which are related to plasmons. The samples are prepared by co-evaporating gold and SiO2 in various proportions on glass slip covers. The films will be sufficiently thin, approximately 50 nm, to allow some transmission of an optical beam. The samples will be attached, film-side outward, to the large face of a right-angle prism with index-matching fluid such as glycerin for the optical experiments described below.
