Low temperature TiO2 rutile phase thin film synthesis by chemical spray pyrolysis (CSP) of titanyl acetylacetonate

Characterization of sprayed TiO2 on ITO substrates for solar cell applications

“…It suggests that the compressive stress is generated during the deposition due to reduction in the crystal defects. The increasing substrate temperature increases the atomic mobility and reduces the structural defects and thus decreased in the stress [6,18]. For the films deposited at 475°C, the obtained stress is increased and this is due to the change in morphology of the film [21].…”

“…The decrease in strain indicates the decrease in concentration of lattice imperfections, and the formation of high quality film [20]. Whereas at the substrate temperature 475°C, the crystallite size decreases with increase strain and dislocation density which may be due to the phase transformation [6].…”

“…Higher surface kinetic energy at 450°C permits a better accommodation in the preferred orientation with higher grain size. The strong preferred orientation of (1 0 1) plane of anatase phase of TiO 2 is due to the Ti and O 2 atoms which are easily accommodated at lower energy [6]. At 475°C, the intensity of anatase peak is decreased with the appearance of rutile peak of (1 1 0) plane.…”

“…Furthermore material has more chemical stability and non-toxicity due to its environmental purification phenomenon [5]. The has specific properties such as high transparency in UV-visible region, high refractive index and stability of the chemical composition presented by TiO 2 make then to be used as photoelectrode in the dye-sensitized solar cells (DSSC) [6]. The dye-sensitized solar cell is also called Graztel cell.…”

Solar light induced rhodamine B degradation assisted by TiO2–Zn–Al LDH based photocatalysts

“…This phase together with ZnO phase in samples highly contributes to photocatalytic properties and was also detected by XRD analysis [20,31]. The bands related to the presence of ZnO and Zn 2 TiO 4 phases were not detected in IM_ZnAl_1Ti sample, but a broad and wide peak was detected at $505 cm À1 that can be attributed to the Ti-O-Ti vibrations of the crystal anatase TiO 2 phase [55][56][57]. The FT-IR analysis additionally confirmed the overall presence of the phases detected by XRD analysis.…”
