TL;DR: In this article, it was shown that Mn+−TiO2 crystallizes into anatase or rutile structures depending on the type and amount of cations present in the film and the local environment around the different cations has been ascertained by X-ray absorption spectroscopy.

TL;DR: In this article, the influence of sample characteristics such as crystallinity and microstructure on photo efficiency of TiO2 in the form of thin films has been investigated, and the results showed that the anatase structure, a high porosity, and a columnar-type growth of the thin films are beneficial factors favoring the photoefficiency of the system.

TL;DR: In this paper, the formation of Si-O-Ti bonds and a change in the environment around titanium from four-to six-coordinated has been proved by vibrational and X-ray absorption spectroscopies.

TL;DR: In this article, the incorporation of nitrogen within the structure of TiO2 thin films has been accomplished by N2+ ion implantation in anatase thin films (50 keV ion energy for doses of 3 × 1016, 6 × 1000, and 1.2 × 1017 ions cm-2) and during preparation by metalorganic chemical vapor deposition (MOCVD) using nitrogen as carrier gas.

TL;DR: A theoretical model to determine the effective dielectric tensor of heterogeneous materials composed by anisotropic microcrystallites has been introduced to explain the infrared spectral features of textured thin films of uniaxial materials as the function of a textural parameter as mentioned in this paper.
