Abstract
In this work, we report a controlled self-assembly of three M13 icosahedral building-blocks into cyclic Pt3Ag33 or Pt3Au12Ag21 nanoclusters. Compared to the previously reported Pt2Ag23 and Pt1Ag12 nanoclusters, the Pt3Ag33 nanoclusters exhibit a red-shift in both the optical absorption and photoluminescence due to the assembly of an additional Pt1Ag12 icosahedron.
