Abstract The structure and properties of Ag self-assembly films have attracted much attention in the past decade, which are to a large extent influenced by the structure and properties of the nanoparticles. In the present work, the single-layer and multi-layer complex films of silver nanoparticles and their absorbates were fabricated by using self-assembly technique. The interaction of silver nanoparticle and its absorbate was studied using absorption spectroscopy and surface enhanced Raman scattering spectroscopy. The Raman enhanced properties of silver nanoparticles, and the structure and properties of the complex films were also investigated. The experimental results indicate that the interaction of octodecyl amic (OA) and silver nanoparticle takes place via the NH2 substitute and the active site on Ag, and there might exist photocatalysis under the laser excitation. In addition, the product from otcodecyl amic and stearic acid(SA) has a weak interaction with silver nanoparticle, which mainly takes place as spatial encumbrance in the self-assembly complex film.
