Au₁₀Ag₁₇(TPP)₁₀(SR)₆Cl₅nanocluster: structure, transformation and the origin of its photoluminescence

Abstract

Nanocluster photoluminescence (PL) has important practical applications and its rationalization is therefore of significant interest. Here, we report the synthesis, structure determination and photoluminescence of Au10Ag17(TPP)10(SR)6Cl5 (TPP = triphenylphosphine, SR...

An Au5Ag12(SR)9(dppf)4 alloy nanocluster: structural determination and optical property and photothermal conversion investigation

“…S9†). 59 This packing mode is consistent with that observed in Au 5 Ag 11 and Au 7 Ag 8 nanoclusters (Fig. S10 and S11†), but it differs from the “ABC” packing mode found in the Au 4 Ag 13 nanocluster (Fig.…”

Atomically precise M 15 (M = Au/Ag/Cu) alloy nanoclusters: Structural analysis, optical and electrocatalytic CO 2 reduction properties

“…Research on such alloy nanoclusters has attracted increasing attention in previous studies [11,20,28,31,33,[38][39][40][41]. From these studies, a preliminary understanding of the origin of the optical properties of metal nanoclusters is obtained, and theoretical guidance for designing nanoclusters with high photoluminescence quantum yields (PLQYs) is provided [4,40,42,43].…”

[Au9Ag6(CCR)10(DPPM)2Cl2](PPh4): a four-electron cluster with a bi-decahedral twisted metal core

“…43 The centered icosahedron serves as a classic assembly component. To date, many Au, Ag or their alloy clusters, featuring metal cores with rod-shaped bi-icosahedral, [44][45][46][47][48] rod-shaped tri-icosahedral, 49,50 ring-shaped tri-icosahedral, 43 rod-shaped tetra-icosahedral, 51 or ring-shaped penta-icosahedral structures, 52 have been reported. The Wang group reported an Au cluster, [Au 24 (CuCPh) 14 (PPh 3 ) 4 ](SbF 6 ) 2 , which contains two cuboctahedral units by sharing of faces.…”
