Abstract
The formationof Au25@SiO2 is reported in which the quantum clusters (QCs) are embedded in a layer of silica. Polydisperse AumSGn QCs are converted rapidly into monodisperse Au25 QCs by the addition of (3-mercaptopropyl)trimethoxysilane (MPTS) with ≈7-times-higher yield when compared to the glutathione-mediated synthesis. Subsequent hydro-lysis and condensation results in the formation of Au25@SiO2.
