A seedy route: monodisperse CuAu and Cu(3) Au nanocrystals (NCs) were fabricated by a seed-based diffusion route using Au NCs as precursors. This method has advantages in controlling the size and monodispersity of the products. Moving a solid-state reaction into solution may help to achieve homogeneous diffusion and require less time and thermal energy.
