Abstract We characterized optical properties of single platinum-coated core-shell gold nanorods (Pt-AuNRs) under dark-field (DF) and differential interference contrast (DIC) microscopy. Furthermore, we examined their potential use as multifunctional orientation probes. The longitudinal surface plasmon resonance damping is observed for single Pt-AuNRs due to Pt metals coated on the AuNR surface under single particle scattering spectroscopy. Despite the strong plasmon damping with much decreased scattering intensity, DIC microscopy allowed us to detect single Pt-AuNRs with much higher sensitivity. We found polarization-dependent DIC images and intensities of single Pt-AuNRs, which allows us to determine their orientation angle under DIC microscopy.
