A SERS-active system based on silver nanoparticles tethered to a deposited silver film

Article Abstract:

A series of surface enhanced Raman spectroscopy (SERS)-active nanostructures are produced by exposing a freshly deposited silver film to a solution containing a mixture of 1-decanethiol (m) and 1,9-nonaedithiol (d) of varying concentrations. The nanoparticle-metal film system is a simple embodiment of a more general range of SERS-active sensing platforms in which a molecular tether is used to create a SERS hot spot that is large enough to accommodate analyte molecules that cannot themselves function as linkers.

The role of [O.sub.2] in SERS-active thin metal film photodynamics

Article Abstract:

An analysis of optical emission from thin Ag films excited by visible light under a non-oxygen atmosphere was carried out as a function of time and excitation power. The evidence obtained strongly supports the hypothesis that oxygen plays a key role in the blinking phenomenon observed on surface enhanced Raman spectroscopy (SERS)-active Ag films.
