Direct Evidence of High Spatial Localization of Hot Spots in Surface-Enhanced Raman Scattering

Hot and cold: The high degree of localization in SERS hot spots is demonstrated directly by a selective deposition of Raman analytes inside and outside the field‐enhanced regions in a plasmonic cavity (see picture). The localization is demonstrated by measurements of both the absolute SERS intensiti...

Zusammenfassung:Hot and cold: The high degree of localization in SERS hot spots is demonstrated directly by a selective deposition of Raman analytes inside and outside the field‐enhanced regions in a plasmonic cavity (see picture). The localization is demonstrated by measurements of both the absolute SERS intensities and the kinetics for photoinduced degradation at different positions.
