The magnetic properties of the Ni@Au core–shell NPAs were analyzed and the saturation magnetization (Ms) of the Ni80@Au20 nanoparticles was found higher than that of nickel-only nanoparticles with the same diameter. The surface enhanced Raman scattering (SERS) property of the Ni@Au core–shell NPAs was then examined using the Rhodamine 6G (R6G) as a Raman reporter molecule and a SERS enhancement factor of 2.5×106 was achieved on the Ni50@Au50 NPA substrate, which was of 9 times higher than that for Au nanoparticles with the same size distribution. It was due to the enhanced local surface plasmon resonance (LSPR) between the ferromagnetic Ni cores and the surface polariton of Au shells of each nanoparticle. The fabrication of the Ni@Au core–shell NPAs with different compositions offers a new avenue to tailor the optical and magnetic properties of the nanostructured films for chemical and diagnostic applications.\nKeywords: surface enhanced Raman scattering; magnetic-plasmonic nanoparticles; core-shell nanoparticles; ferromagnetic nanoparticles.\n| Format: DOCX | Size: 3.3 MB | Download |\nWhen a peer-reviewed version of this preprint is available, this information will be updated in the information box above.
