title: A metal exchange method for thiolate-protected tri-metal M(1)Ag(x)Au(24-x)(SR)(18)(0) (M = Cd/Hg) nanoclusters.
abstract: We herein reported the first synthesis of tri-metallic M1AgxAu24-x(SR)18(0) (M = Cd/Hg) nanoclusters by a two-step metal exchange method. Optical spectra suggested that the second and third foreign metals could largely change the electronic structure of homogold Au25(SR)18(-) nanoclusters. This work also provides a novel way to find the doping site of some special metals (such as Cd), which can be done using silver as the isotope of gold.
