Gold Doping of Silver Nanoclusters: A 26-Fold Enhancement in the Luminescence Quantum Yield
A high quantum yield (QY) of photoluminescence (PL) in nanomaterials is necessary for a wide range of applications. Unfortunately, the weak PL and moderate stability of atomically precise silver nanoclusters (NCs) suppress their utility. Herein, we accomplished a ≥26‐fold PL QY enhancement of the Ag...

| description | A high quantum yield (QY) of photoluminescence (PL) in nanomaterials is necessary for a wide range of applications. Unfortunately, the weak PL and moderate stability of atomically precise silver nanoclusters (NCs) suppress their utility. Herein, we accomplished a ≥26‐fold PL QY enhancement of the Ag29(BDT)12(TPP)4 cluster (BDT: 1,3‐benzenedithiol; TPP: triphenylphosphine) by doping with a discrete number of Au atoms, producing Ag29−xAux(BDT)12(TPP)4, x=1–5. The Au‐doped clusters exhibit an enhanced stability and an intense red emission around 660 nm. Single‐crystal XRD, mass spectrometry, optical, and NMR spectroscopy shed light on the PL enhancement mechanism and the probable locations of the Au dopants within the cluster.
Die Quantenausbeute (QY) von schwach lumineszierenden Ag29‐Clustern wurde durch die Dotierung der Nanocluster mit einer bestimmten Zahl an Goldatomen 26‐fach verstärkt, während die ursprüngliche Ag29‐Struktur intakt blieb. Eine detaillierte Charakterisierung ergab die Anwesenheit von Goldatomen im Zentrum der Ag29‐Cluster und von vier Phosphan‐Bindungszentren des Ag29‐Clusters, die eine zentrale Rolle für die Verstärkung der QY spielten. |
