Abstract

Structure and optical properties of amorphous diamond-like carbon (a-C: H) thin films modified with Ag, Ti and Ag + Ti metal impurities are studied. The films were prepared by ion-plasma magnetron sputtering of combined polycrystalline graphite and metal target in the mixture of Ar and CH₄ gases. AFM, SEM and TEM methods show that a-C:H<Ag+Ti> films are heterogeneous, nanostructured and characterized by the presence of silver nanoclusters on the surface sized ~ 60 nm and both Ti and Ag nanoclusters with a mean size ~ (2 ÷ 3) nm in the bulk of films. It was found that in a- C:H<Ag+Ti> films as well as in a-C:H<Ag> films plasma resonance absorption due to excitation of surface plasmons in silver nanoclusters in the visible region of spectrum takes place. Intensity of the resonance absorption in the a- C:H<Ag+Ti> films increases with increase in concentration of silver. The results are important for produce of nanomaterials with nonlinear optical properties based on the amorphous diamond-like carbon films containing metal nanoclusters.
