Various nanoparticles such as gold nanocubes, gold nanostars and gold nanorods (AuNRs) have been widely studied during past two decades. Recently, bimetallic core-shell nanoparticles have attracted great attention because of their unique optical properties resulted from localized surface plasmon resonance (LSPR) effect. Furthermore, bimetallic core-shell nanoparticles show unanticipated catalytic properties such as high catalytic activity, catalytic selectivity, and better resistance to deactivation. In this study, we investigated individual Pt-coated AuNRs under single particle spectroscopy without ensemble averaging. More specifically, far-field dark-field (DF) microscopy and differential interference contrast (DIC) microscopy were used to obtain optical images of Pt-coated AuNRs and characterize their optical properties at the single particle level.
