Interfacial etching of silver nanoparticles and separation of the products by polyacrylamide gel electrophoresis afforded Ag 8 and Ag 7 clusters with red and blue‐green fluorescence emission, respectively (see picture). The strongly temperature‐dependent emission of the clusters suggests potential applications, whilst their facile phase transfer to organic media facilitates further studies.
