Quantitatively linking morphology and optical response of individual silver nanohedra

Autor: Yisu Wang, Zoltan Sztranyovszky, Attilio Zilli, Wiebke Albrecht, Sara Bals, Paola Borri, Wolfgang Langbein

Publikováno v: Nanoscale

The optical response of metal nanoparticles is governed by plasmonic resonances, which are dictated by the particle morphology. A thorough understanding of the link between morphology and optical response requires quantitatively measuring optical and
