Abstract

A three-channel spectrometer (3CS) based on a commercial digital camera was developed to distinguish among tens of large (>100 nm), anisotropic plasmonic particles with various shapes, orientations, and compositions on a surface simultaneously. Using band-pass filters and polarizers, we could enhance the contrast of 3CS images to identify specific orientation and composition characteristics of gold and gold-silver nanopyramids as well as the direction of the longest arm of gold nanostars.
