“…It has been observed that TiO 2 films doped with copper [11][12][13], iron [14,15], chromium [16,17], carbon [18,19], nitrogen [20,21] and bismuth [22] improve their properties as photocatalysts in the visible region. However, the antibacterial properties of TiO 2 not only depend on dopants but also other parameters such as crystalline nature, crystalline size, phase composition, chemical composition and synthesis methodology [23].…”

Cu/TiO 2 thin films were deposited on glass substrates by reactive RF magnetron sputtering technique. Crystalline structure, surface morphology and electronic structure were studied using X-ray diffraction (XRD), field emission scanning electron microscopy, atomic force microscopy and X-ray photoelectron spectroscopy (XPS). Transmittance and absorptance of these films were characterized by UV-Vis spectroscopy. XRD patterns demonstrate that TiO 2 films deposited on glass substrate at 300°C are observed to be in pure anatase phase, whereas Cu/TiO 2 films are amorphous in nature at 300°C substrate temperature. The crystallinity of Cu/TiO 2 thin films decreases with increasing the dopant concentrations of Cu in TiO 2 films. XPS studies show that Cu is in ?2 oxidation state in all films. The optical band gap of Cu/TiO 2 films decreases from *3.3 to *2.0 eV with the increase in the copper concentration. Further, antimicrobial studies of Cu/TiO 2 films with *3.9 at.% Cu exhibit high transmittance and best antimicrobial activity against E. coli and S. aureus compared to other doped films.

“…It is well known that niobium doping is effective in enhancing the electrical conductivity of TiO 2 [1,[4][5][6][7]. Other elements such as Fe [8], Ni [9], Pd and V [10], and Cr [11] have been used for doping to control the electrical properties of TiO 2 . Moreover, doping with non-metallic elements such as N [12], F [13,14] and B [15,16] has been also examined to improve the photocatalytic properties of TiO 2 .…”

“…Although many structural and optical studies [4][5][6][7][8] were carried out for TiO 2 , its electron transport properties remain back due to its high resistivity. In fact, in TiO 2 semiconductor thin films having a high energy gap in which compensation is nearly full, impurity band conduction may become significant even above room temperature [9].…”
