Ag/titanium oxide granular composite films with Ag atom concentration in the range of 34% to 69% were prepared by using co-sputtering technique in Ar atmosphere at the pressure of 3.0 × 10−2 Torr. The chemical binding energy of Ag and Ti in the composites was investigated by X-ray photoelectron spectroscopy. The Ag particle size measured by SEM is in the range of 2050 nm. The strong resonant absorption near 860 nm is observed in the composites with 34% atom concentration of Ag, which implies a large enhancement of local field and optical nonlinearity in the co-sputtered Ag/titanium oxide composites.
