Paper Abstract

The controllable preparation of platinum nanoparticles with defined shapes, including sphere, octahedron, octapods and tetrapods, was realized by varying the concentration of NaNO3 in the solvothermal process. NaNO3 plays a critical role in synthesizing Pt nanoparticles with different shapes. These Pt nanoparticles were self-assembled on glass substrates to study the influence of metal nanoparticles' shape on their SERS enhancement using 4-mercaptopyridine as molecules probes. Thanks to the enhanced local field effect around their sharp corners and edges, those Pt tetrapods exhibit enhanced SERS properties than those particles with other shapes.
