Abstract

We present results of a theoretical and experimental investigation into monolayers made of oxidized nanogranules of amorphous copper and their aggregates with a high surface concentration. We show theoretically that the packing density of the nanogranules, the size of aggregates, and the thickness and composition of the oxide layer over a Cu nanogranule affect the shift in the plasma resonance. Experimentally we established a non-monotone dependence of the absorption in the plasma resonance band and the UV spectral range with a high surface packing density of copper nanoparticles. The optical measurements indicated a non-uniform oxidation of the granules on the substrate.
