Surface enhanced infrared absorption (SEIRA) spectroscopy
was investigated using sputtered gold nanoparticles on the As2S3 chalcogenide glass. Islands
films were sputtered on the substrate with various thicknesses from 11.1 +/- 0.9 nm to 31.4 +/-
3.6 nm. Infrared transmission spectra of 4-nitrothiophenol adsorbed on gold nanoparticles show
that SEIRA effect was dependent of the thickness of discontinuous gold films. Only symmetric NO2
stretch (1336 cm(-1)) was observed and enhanced due to surface selection rules. The best
enhancement is one order of magnitude stronger than for a continuous gold film. The corresponding
thickness measured by Atomic Force Microscopy is 16.3 +/- 0.5 nm. (C) 2011 Published by Elsevier
