Abstract

This work shows the enhancement of spectral absorptions by noble metals (Ag, Au) deposited in nm-thick layers on the surface of ATR-crystals. By the surface-enhanced infrared absorption (SEIRA) technique, the absorption bands of p-nitrobenzoic acid can be enhanced by a factor ofup to 40. This enables the detection of substance concentrations in the mM range. The structure of the metal deposit has been investigated by atomic force microscopy and correlated with the enhancement factor.
