Abstract

Gold nanoparticles with an average sizes of 5 nm were interlinked with 1,4-Benzenedithiol to a thin film. For the film preparation manual layer-by-layer spin-coating was used. The composition of the film was analyzed by X-ray photoelectron spectroscopy (XPS) and Surface Enhanced Raman spectroscopy (SERS). The sensing properties of the sample were determined by measuring of changes of the resistance under the influence of different vapors (toluene, water, 1-propanol and 4-methyl-2-pentanone). The film showed linear I-V characteristics at room temperature.
