Effect of Metal (Ni2+, Fe3+, and Mo3+) Doping in TiO2 Thin Films on Antimicrobial Activity
Pure- and metal (Ni2+, Fe3+, and Mo5+)-doped TiO2 films were prepared on soda-lime-silica glass by a spin coating-pyrolysis, to be used in antimicrobial applications. As-deposited films were prefired at 500 °C for 10 min in air, followed by annealing at 550 °C for 60 min in argon. X-ray diffraction, field emissionscanning electron microscopy, and ultra-violet-visible-near infrared spectrophotometry were used to analyze the crystal structure, surface morphology, and optical properties of the films, respectively. The largest red shift in the optical-energy band gap was obtained on the Fe3+-doped TiO2 film after annealing. The number of Escherichia coli that remained after each irradiation time was counted to examine the antimicrobial ability of the films. A reduction of above 99% of Escherichia coli populations on 10 mol% Fe3+-doped TiO2 films was observed after irradiation for 40 min at 375 nm.
