Effect of Er doping on the microstructural, optical, and photocatalytic activity of TiO₂ thin films

Fabrication of TiO2 based Dye-Sensitized Solar Cell using Nerium oleander as a sensitizer

“…The as-prepared anatase TiO2 show a wide band gap that may find application in photovoltaic devices, anti-reflective (AR) coatings for solar cells and optoelectronic devices especially as a gate in metal-oxide-semiconductor (MOS) transistor [4,22,23]. The Er 3+ ion may have replaced the Ti 4+ ion in 1 mol% Er-doped TiO2, resulting in a narrower band gap that can be utilized for photocatalytic activity [24,25].…”

Synthesis, structural, photocatalytic, wettability and optical properties of TiO2 films on polymethyl methacrylate substrates

“…TiO 2 is one of the most usable oxides in industrial applications and in various fields such as photovoltaic [1], photocatalytic degradation of organic wastes [2][3][4][5][6], self-cleaning [7], gas sensing [8], ultra-violet (UV) photodetecting [9], hydrogen generation [10,11], etc. The photocatalytic property of TiO 2 coatings is the most common and widely used in industry because of their high efficiency in degradation of organic pollutants upon UV illumination [12][13][14].…”

Synthesis, Characterization, and Antibacterial Activity of Ag–TiO2–Fe Composite Thin Films

“…[ 11–15 ] Furthermore, they could enhance the photocatalytic activity in the visible light region and increase the antibacterial performance. [ 6,16,17 ] Ag is one of the most interesting materials due to their excellent physical and chemical properties, catalytic activity, and low toxicity. [ 18,19 ] It is well known as antibacterial agent from ancient time.…”

“…[11][12][13][14][15] Furthermore, they could enhance the photocatalytic activity in the visible light region and increase the antibacterial performance. [6,16,17] Ag is one of Ag-TiO 2 -Fe composite thin films with different Ag contents are deposited onto a glass substrate by a thermal evaporation method. TiO 2 , TiO 2 -Fe, and Ag-TiO 2 -Fe thin films are characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), UV-vis-NIR spectroscopy, and photoluminescence (PL) to study the relation between their structural, morphological, optical, and luminescent properties with their antibacterial activities.…”
