    Femtosecond optical nonlinearities of Au/TiO2 thin films prepared by a sputtering method

    A multitarget sputtering method was applied to embed Au nanoparticles in TiO2 thin films (Au/TiO2 films) with a high concentration of Au particles (19–41 at%). The absolute values of imaginary part of the third-o...

    Localized surface plasmon resonance sensing properties of photocatalytically prepared Ag/TiO2 films

    Photocatalytic deposition of Ag nanoparticles from a mixed aqueous solution of AgNO3 and polyvinylpyrrolidone (PVP) onto TiO2 film supported on indium-tin oxide-coated glass slide (Ag/TiO2 film) was carried out b...

    Preparation and femtosecond non-linear optical properties of Ag/SiO2 composite thin films

    Ag nanoparticles embedded in SiO2 thin films (Ag/SiO2 films) were prepared by a multitarget sputtering method. In the optical absorption spectra of the Ag/SiO2 films, the absorption peak due to the surface plasmo...
