英文摘要 | Pt nanodots were formed oil au nanorods (nrs) by using a simple seed-mediated growth. their density and distribution on the au nr can he finely tuned by varying the reaction parameters. at lower pt/au ratios, the pt nanodots mainly appear at endcaps and side edges of the au rod. at higher pt/au ratios, they distribute homogeneously over the whole au rod. the obtained pt nanostructure is a single crystal owing to the epitaxial growth of pt on the au rod. due to the unique surface plasmon resonance (spr) features of the au nrs. the au core/pt shell (au@pt) nanostructures also exhibit well-defined and red-shifted longitudinal spr hands in the visible and near-infrared region. the position and intensity can be regulated by the thickness and amount of the pt shell. at a thinner pt thickness, the au@'pt nrs show higher dielectric sensitivity than the corresponding au nrs. it thus opens up the potential of pt nanostructures for spr-based sensing. |
