Abstract

Au nanoparticles (Au NPs) multilayer structures have been fabricated by an alternate deposition of a bifunctional dithiol cross-linker and Au NPs, to analyze the localized surface plasmon resonance spectra and the refractive index sensitivity to terpene vapors. UV-vis spectroscopy and atomic force microscopy (AFM) have been used to characterize the obtained multilayer structures. The investigations show that the number of Au NPs deposition cycles has effects on the multilayer structure fabrication and the refractive index sensitivity of the sensor.
