Paper Abstract
Bipyramidal gold nanorods have received a large amount of interest as a plasmonic nanomaterial due to highly localised field at their tips, which provide enhancement for emission processes. However, no proper evaluation of geometrical properties of bipyramids such as tip shape, curvature, pentagonal cross section or the waist have been conducted on the field enhancement and peak evolution. Here we present a full numerical simulation of field enhancement around bipyramidal gold nanorods with variation in geometry. We also present a simple analytical theory based on prolate spheroids to account for bipyramidal shape with correction factor to approximate the shape difference.
