Photoreactivity of As-fabricated Au clusters at the single-cluster level.
In this study, we have photochemically fabricated a gold cluster (Au(n)), composed of several tens of atoms, in a polymer matrix and concurrently investigated the photoreactivity of newly formed clusters at the single-cluster level. Our attempt enabled the in situ observation of individual ligand-free Au(n) clusters with a resolution of the number of atoms. In addition, the procedure revealed the photoinduced reaction of excited Au(n) clusters with O(2) for the first time.
