Plasmon-Mediated Synthesis of Heterometallic Nanorods and Icosahedra

Plasmon-Mediated Synthesis of Heterometallic Nanorods and Icosahedra

Bimetallic nanoparticles: Au–Ag core–shell heterometallic nanorods and icosahedra can be prepared from Au decahedral seed particles using plasmon‐mediated synthetic methods and adjusting the pH value of the solution (see picture). This method allows for the preparation of icosahedral nanostructures...

Zusammenfassung:Bimetallic nanoparticles: Au–Ag core–shell heterometallic nanorods and icosahedra can be prepared from Au decahedral seed particles using plasmon‐mediated synthetic methods and adjusting the pH value of the solution (see picture). This method allows for the preparation of icosahedral nanostructures with an asymmetric metal distribution.
