A remarkable enhancement of Raman scattering is achieved by submicrometer‐sized spherical ZnO superstructures. The secondary superstructures of ZnO particles with a uniform diameter in the range of 220–490 nm was formed by aggregating ca. 13 nm primary single crystallites. By engineering the superstructure size to induce Mie resonances, leading to an electromagnetic contribution to the SERS enhancement...
Submikrometer‐große Halbleiter‐Superstrukturen können als hoch effiziente, SERS‐aktive (SERS=oberflächenverstärkte Raman‐Streuung) Substrate genutzt werden, die W. Ji, B. Zhao, Y. Ozaki et al. in ihrer Zuschrift auf S. 14594 beschreiben. Die Superstruktur ermöglicht einen Synergieeffekt für die SERS‐Verstärkung durch Kopplung von Ladungstransfer und Mie‐Resonanz, was zu einem Verstärkungsfaktor von...
