Reversible temperature dependence in surface-enhanced Raman scattering of 1-propanethiol adsorbed on a silver island film

Article Abstract:

A reversible increase of the surface-enhanced Raman scattering (SERS) intensity as the surface temperature was lowered was observed in a measurement over the 15-300 K surface temperature range of SERS intensity of 1-propanethiol adsorbed on a silver film prepared chemically. A variety of factors that can possibly influence the SERS intensity could be ruled out as the cause for such temperature dependence. The observed temperature dependence can be explained quantitatively within the framework of the electromagnetic model.

Temperature dependence and annealing effects in surface-enhanced Raman scattering on chemically prepared silver island films

Article Abstract:

It has been possible to identify a reversible temperature dependence for the surface-enhanced Raman scattering intensities of ethanethiol adsorbed on a chemically prepared silver film with the intensity at 15 K being greater than that at 300 K by a factor of around 2.5.

Remarks on the substrate-temperature dependence of surface-enhanced Raman scattering

Article Abstract:

Research concerning the use of surface-enhanced Raman scattering (SERS) to investigate the effect of temperature on the plasmon frequency of metal is presented. The dependence of SERS on substrate temperature is discussed.
