文摘
- •
Ag nanoparticles (Nps) embedded in TiO2 matrix were prepared by magnetron sputtering.
- •
Increased working pressure of Ag led to blue-shift of SPR peaks of Ag Nps.
- •
TiO2 showed enhanced Raman scattering due to strong local field induced by Ag Nps.
- •
Photogenerated carriers separation in TiO2 film was improved by embedded Ag Nps.
