The concentration of Ag, determined by XPS and WDS, moved from zero to ~ 10 at%. We found that the sp2/sp3 ratio, film roughness and the number of droplets (SEM and AFM) increased with increasing silver concentration. The sp3 content measurement (XPS) was influenced by ion cluster surface sputtering and varied from 71.0% (undoped DLC) to 36.2% (for 9.3 at% Ag). Transmission was measured on the scale from 200 nm to 1100 nm, and decreased with increasing silver content. An increase of Ag content has an effect on the decrease of the storage modulus (E′) and the indentation hardness (HIT).
