Silver colloidal nanoaggregates have been widely used for surface‐enhanced Raman scattering (SERS) measurements. SERS‐active nanoaggregates generally show monotone colors, although multicoloured‐blinking emissions, which occur at the single‐molecule level, have been observed from each Ag colloidal nanoaggregate with poly‐L‐lysine.

We found large spectral changes in surface-enhanced resonance Raman scattering (SERRS) with increasing refractive index of media around single Ag nanoaggregates. We analyzed relationship between the spectral changes in SERRS and those in plasma (plasmon) resonance based on the twofold electromagnetic (EM) enhancement theory.

We found a binary active site of surface enhanced Raman scattering (SERS) and surface enhanced hyper Raman scattering (SEHRS) in single Ag nanoaggregates by single particle spectroscopy. The intensity fluctuation of SEHRS was canceled by dividing SEHRS intensity by SERS intensity on the basis of the binary active site analysis.

In this paper we report the study of down-shifting silica-zirconia glass and glass-ceramic films doped by Tb3+ions and Ag nanoaggregates, which combine the typical spectral properties of the rare-earth-ions with the broadband sensitizing effect of the metal nanostructures. Na-Tb co-doped silica-zirconia samples were obtained by a modified sol-gel route.
