The order of gold: Ordered assemblies of gold nanostructures are produced by droplet evaporation from single- and two-component systems. The ordering of the assemblies is highly dependent on the shape and size of gold nanostructures and includes nanorods, nanocubes, polyhedra, and bipyramids. The two-photon-excited luminescence of ordered gold nanorod assemblies is larger than that of disordered nanorod assemblies.
