Nanocrystals: Fabricating a Homogeneously Alloyed AuAg Shell on Au Nanorods to Achieve Strong, Stable, and Tunable Surface Plasmon Resonances (Small 39/2015)

The epitaxial growth of homogeneously alloyed AuAg shells on Au nanorods is achieved by Y. Han and co-workers via a precisely controlled synthesis. On page 5214, they show how the resulting core–shell-structured bimetallic nanorods integrate the merits of the AuAg alloy with the advantages of anisotropic nanorods, exhibiting strong, stable, and tunable surface plasmon resonances.
