Structural, morphological and optical properties of thermal annealed TiO thin films

Sol-Gel Preparation of Nanoscale TiO<sub>2</sub>/SiO<sub>2</sub> Composite for Eliminating of Con Red Azo Dye

“…The shift can be attributed to the difference in grain size in these samples. Zribi et al obtained similar evolution of optical band gap with the temperature and concluded that the variation of density and the structural modifications may be responsible for changes in the shape of the fundamental absorption edge [29]. According to Figure 3 a peak corresponding to isolated Ti species which have absorption maxima at about 225 nm is observed in composite spectra.…”

Effect of high roughness on a long aging time of superhydrophilic TiO2 nanoparticle thin films

“…show SEM images of the as-deposited NP thin films and the annealed samples (annealed at 250, 500 and 750 C for 1 h in air), respectively. It is noted that the secondary particle sizes slightly increased [22,23] with increasing annealing temperature (Table 1). Although the SEM images show that the secondary particle sizes were in the range of 26e36 nm, the high magnification TEM image (Fig.…”

Morphological effects on IR band profiles

“…In addition, when a deposited TiO thin film underwent annealing in air, anatase and rutile structures have been shown at a temperature of 793 K (Zribi et al 2008), which indicates possible TiO 2 formation from TiO via an annealing process.…”
