Abstract
ABSTRACTTiO2 thin film synthesized by the RF sputtering method has been implanted by 120 keV Ag− ion with different doses (3 × 1014, 1 × 1015, 3 × 1015, 1 × 1016 and 3 × 1016 ions/cm2). Further, these were characterized by Rutherford back Scattering, XRD, X-ray photoelectron spectroscopy (XPS), UV–visible and fluorescence spectroscopy. Here we reported that after implantation, localized surface Plasmon resonance has been observed for the fluence 3 × 1016 ions/cm2, which was due to the formation of silver nanoparticles. Ag is in metallic form in the matrix of TiO2, which is very interestingly as oxidation of Ag was reported after implantation. Also, we have observed the interaction between nanoparticles of Ag and TiO2, which results in an increasing intensity in lower charge states (Ti3+) of Ti. This interaction is supported by XPS and fluorescence spectroscopy, which can help improve photo catalysis and antibacterial properties.
