Abstract
Description
technical field
[0001] The invention relates to a single-crystal gold core / palladium shell structure bimetal nanorod and a preparation method thereof. The method realizes the epitaxial growth of a rectangular palladium shell structure on a cylindrical gold core structure by controlling the reaction process. Background technique
[0002] For metal nanoparticles, size, composition, crystallinity, shape and structure have a significant impact on their properties, especially optical properties. Since the mid-nineties, shape-controlled synthesis has attracted much attention because in many cases it is easier to achieve fine tuning of material properties than several other factors. For example, existing research work has shown that the peak position and number of plasmon resonance peaks on metal surfaces and the effective spectral range of surface-enhanced Raman scattering can be tuned by controlling the shape of metal nanostructures. Therefore, the shape-controlled synthesis has...
