Structural and optical properties of TiO2 thin films derived by sol–gel dip coating process

Photocatalytic and electrooxidation properties of TiO2 thin films deposited by sol–gel

“…1c) are in good agreement with the JCPDS card (No. 84-1286) for the crystal structure of anatase [31,13,[32][33][34][35]. It can be observed that both 3× and 4× TiO 2 thin films show narrow XRD reflections with significantly higher intensity than the corresponding 1× TiO 2 sample, indicating, in general, enhanced crystallinity of the TiO 2 thin films with increasing thickness.…”

Structural and spectroscopic study of the Fe doped TiO2 thin films for applications in photocatalysis

“…The concentration of Fe utilized for doping ranged from 0.5 to 4 % by atomic weight. For lower concentrations of Fe the transformation from amorphous-to-polycrystalline occurred at 400 o C. However, as the Fe concentration was increased to 4% this transformation occurred only after annealing at 600 o C. [16]. In our study we have prepared sols with different concentrations of Fe: 0, 1, 2, 3, and 4 wt% by adding different amounts of ferric nitrate.…”

Dielectric Measurements on Sol–Gel Derived Titania Films

“…1 Titania exists in a number of crystalline forms, the most important of which are anatase, rutile and brookite, and the high optoelectronic properties of non-toxic oxides are found to be a phase-dependent quantity. 2,3 Thin film formulation of the materials can be achieved by using different techniques including DC reactive magnetron sputtering 4 and electrodeposition. 5 The magnetron-sputtered TiO 2 layers on aluminium alloy 1050 substrates showed columnar growth with increasing crystallite sizes, with an increase in coating thickness leading to an increase in photocatalytic activity.…”
