Abstract

In present work, we report the synthesis of Ag-TiO₂ nanocomposite thin films and their modification by swift heavy ions (SHI). Co-sputtering of silver together with titanium oxide (TiO₂) was used to produce Ag-TiO₂ nanocomposite coatings, where Ag nanoparticles are embedded in TiO₂ matrix. The Ag-TiO₂ nanocomposite films (thickness ~35nm) with silver-volume-fraction between 10 and 40 % were prepared by co-sputtering of Ag and TiO₂ using two different sources. Microstructural, optical and antibacterial properties of nanocomposite films were studied. Swift heavy ions were used to engineer different properties of nanocomposites.
