Electronic Structure of Ligand-Passivated Gold and Silver ...

Gold and silver nanoclusters have unique molecule-like electronic structure and a nonzero HOMO-LUMO gap. Recent advances in X-ray crystal structure determination have led to a new understanding of the geometric structure of gold nanoparticles, with significant implications for electronic structure. The superatom model has been effectively employed to explain properties such as one- and two-photon

Systematically Tuning the Electronic Structure of Gold ...

01/08/2019  We track the evolution of highly‐resolved electronic absorption spectra of gold nanoclusters with precisely mass‐selected chemical composition in a controlled environment. Simple derivatization of the ligands yields larger spectral changes than varying the overall atomic composition of the cluster for two clusters with similar symmetry and size. The nominally metal‐localized

26/08/2003  The structures of pure gold and silver clusters (Auk, Agk, k = 1−13) and neutral and anionic gold−silver binary clusters (AumAgn, 2 ≤ k = m + n ≤ 7) have been investigated by using density functional theory (DFT) with generalized gradient approximation (GGA) and high level ab initio calculations including coupled cluster theory with relativistic ab initio pseudopotentials. Pure Auk clusters favor 2-D planar configurations, while pure Agk clusters favor 3-D structures.

30/10/2015  The atomic number of gold ( Au) is 79. Therefore, its ground state electron configuration should have a total number of 79 electrons (add all the superscripts). I have inputted two answers simply because Au is one of those elements who does not follow the predicted order of the electron configuration (the other elements are Cu, Ag, P d, Cr, and M o ...

The Electronic Structure of Platinum-Gold Alloy Particles ...

The electronic structure of the entire particle is averaged over all the atoms, and therefore depends on the fraction of atoms not having a full complement of neighbours; physical properties can then be correlated with the average number of bonds formed between neighbours. As a rough guide one may say that, moving downward in size, one begins to notice changes at about 3 nm, and they become rapid at about 2 nm. A spherical particle

Electronic structures of halogen bridged mixed-valence (MV) complexes Cs 2 Au 2 X 6 (X=I, Br, and Cl) have been investigated by means of reflectivity measurements. We have observed five polarization-dependent optical transitions in the energy range of 0.6-5.5 eV. The lower-lying three bands below ~3 eV are due to the intermolecular transitions from AuX-2 to AuX

Gold - Wikipedia

Gold is the most malleable of all metals. It can be drawn into a wire of single-atom width, and then stretched considerably before it breaks. Such nanowires distort via formation, reorientation and migration of dislocations and crystal twins without noticeable hardening. A single gram of gold can be beaten into a sheet of 1 square metre (11 sq ft), and an avoirdupois ounce into 300 square feet ...

Well almost, but the exceptions are instructional ...
