## Description

- description: Gold ultrathin nanorods (Au UNRs) are anisotropic nanostructures constructed
    by attaching gold nanoclusters in one dimension. Au UNRs exhibit localized surface
    plasmon resonance (LSPR) only in the longitudinal direction because their diameter
    is smaller than the Fermi wavelength of an electron (<2 nm). In this study, we
    found that the LSPR wavelength of oleylamine-stabilized Au UNRs is blue shifted
    simply by mixing with Ag(I). High-resolution elemental mapping and X-ray photoemission
    spectroscopy of the resulting UNRs indicate that an Ag monoatomic layer is formed
    on the Au UNR surface by the antigalvanic reduction of Ag(I). This process allowed
    us to synthesize a series of Au@Ag core-shell UNRs with LSPR wavelengths in the
    range of 1.2–2.0 μm.
