Gold in glass: Activating gold silicate glasses with synchrotron X‐rays results in the spatial reduction of cationic gold to gold atoms. Subsequent annealing allows the growth of nanoparticles with defined sizes and tailored optical properties (see picture). This opens up new vistas in functionalizing chemically and mechanically stable glasses for integrated nanophotonic applications.
