Resumé

In the present work diamond like carbon (DLC) films with embedded Cu nanoparticles were researched. The spectral characteristics of Cu nanoparticles, Cu-CuO and Cu-Cu2O nanoshells and nanocomposites on their base were studied including effects of size of nanoparticles. These studies included experimental research and theoretical simulations based on Bruggeman effective medium theory and dipole equivalence method. It is shown that experimentally observed relatively small redshift of the absorption peak of the DLC:Cu, having place for a wide range of Cu atomic concentration and Cu nanoparticle size, is mostly due to the oxidation of embedded copper nanoparticles.
