Understanding the Photoelectrochemical Behavior of Metal Nanoclusters: A Perspective. This article is cited by 17 publications. The work provides a paradigm that the NCs with continuous metal atom numbers are accessible and crystallizable when meticulously designed, and the optical properties are more affected at the single atom level than the electronic properties.
A.T.O.M. SHOW SERIES
By contrast, little change in both ionization potential and electron affinity is found in this series of NCs by theoretical calculations, indicating the electronic properties are independent of adding a single atom in this series. The photoexcited carrier lifetime demonstrates that the optical properties and excited state relaxation are highly sensitive at the single atom level. A single Cd atom triggers the structural transition from Au 22 with a 10-atom bioctahedral kernel to Au 22Cd 1 with a 13-atom cuboctahedral kernel, and correspondingly, the optical properties are dramatically changed. Structurally, Au 22(SAdm) 16 has an Au 3(SAdm) 4 surface motif which is longer than the Au 2(SAdm) 3 on Au 21(SAdm) 15, whereas Au 22Cd 1(SAdm) 16 lacks one staple Au atom compared to Au 24(SAdm) 16 and thus the surface structure is reconstructed. Here, we report crystallizations of Au 22(SAdm) 16 and Au 22Cd 1(SAdm) 16 (SAdm = adamantanethiolate) which link up with Au 21(SAdm) 15 and Au 24(SAdm) 16 NCs and form an atom-by-atom evolving series protected by the same ligand. Atom-by-atom manipulation on metal nanoclusters (NCs) has long been desired, as the resulting series of NCs can provide insightful understanding of how a single atom affects the structure and properties as well as the evolution with size.
