Visible Luminescence of Water-Soluble Monolayer-Protected Gold Clusters
Abstract
A highly efficient, visible wavelength (λ MAX = 700 to 800 nm) fluorescence is reported for four water-soluble monolayer-protected gold clusters (MPCs). For 451 nm excitation, the quantum yield of the luminescence of MPCs with 1.8 nm diameter cores and protected by monolayers of tiopronin thiolate is estimated as 0.003 ± 0.001. The efficiency and wavelength of the luminescence vary with the ligands of the monolayer around the gold core. The mechanism for the luminescence is hypothesized to be associated with interband transitions between the filled 5d 10 band and 6(sp) 1 conduction band.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
