“…TiO 2 thin films can be prepared by different techniques such as reactive magnetron sputtering [7], sol-gel [8] and pulsed laser deposition (PLD) [9]. In the present study preparation of nanostructured titanium dioxide thin films using pulsed laser ablation technique in reactive atmosphere is discussed.…”

Nanostructured titanium dioxide thin films were prepared using reactive pulsed laser ablation technique. Effects of annealing on the structural, morphological, electrical and optical properties are discussed. The structural, electrical and optical properties of TiO 2 films are found to be sensitive to annealing temperature and are described with GIXRD, SEM, AFM, UV-Visible spectroscopy and electrical studies. X-ray diffraction studies showed that the as-deposited films were amorphous and at first changed to anatase and then to rutile phase with increase of annealing temperature. Optical constants of these films were derived from the transmission spectra and the refractive index dispersion of the films, subjected to annealing at different temperatures, is discussed in terms of the single oscillator-Wemple and Didomenico model.

“…After the probe ssDNA was immobilized on the MWNTs/CeO 2 /CHIT modified electrode, the peak current decreased obviously (curve e). The reason seems to be related to the electrostatic repulsion between the polyanionic DNA immobilized on the electrode and the anionic redox couple ions ([Fe(CN) 6 ] 3À/4À ) [26].…”

“…At the same time, nanoscaled CeO 2 , as a kind of ceramic oxide materials, has also attracted extensive attention owing to its wide applications such as luminous material, catalysts, electronic ceramics, irradiation protectors, polishing materials, etc. [6,7]. So far, reports on nanoscaled CeO 2 materials have mainly focused on its synthesis [8][9][10][11].…”

A porous composite film was fabricated combining the advantages of multiwalled carbon nanotubes, CeO 2 and chitosan. The synergistic effect of the film improved the immobilization of probe ssDNA. The loaded probe ssDNA was used for detection of CdSe quantum dots labeled target DNA. The DNA hybridization reaction was detected by differential pulse anodic stripping voltammetry of Cd 2 + after the oxidative release of labeled CdSe quantum dots. The established DNA biosensor can discriminate different target sequences associated with 35S promoter of cauliflower mosaic virus gene with relatively wide linear range and low detection limit (2.4 10 À13 mol/L).

“…TiO 2 films can be deposited or grown on substrates such as Si, glass, sapphire, and quartz by using reactive sputtering, sol-gel spin coating, laser deposition, thermal evaporation, thermal oxidation of titanium, chemical vapor deposition and chemical spray pyrolysis techniques [7,[9][10][11][12]. The structural characteristics of TiO 2 films are affected by gas pressure and substrate temperature during the deposition process [13].…”

Titanium dioxide (TiO 2 ) thin film was deposited on n-Si (100) substrate by reactive DC magnetron sputtering system at 250 °C temperature. The deposited film was thermally treated for 3 h in the range of 400-1000 °C by conventional thermal annealing (CTA) in air atmosphere. The effects of the annealing temperature on the structural and morphological properties of the films were investigated by X-ray diffraction (XRD) and atomic force microscopy (AFM), respectively. XRD measurements show that the rutile phase is the dominant crystalline phase for the film annealed at 800 °C. According to AFM results, the increased grain sizes indicate that the annealing improves the crystalline quality of the TiO 2 film. In addition, the formation of the interfacial SiO 2 layer between TiO 2 film and Si substrate was evaluated by the transmittance spectra obtained with FTIR spectrometer. The electronic band transitions of as-deposited and annealed films were also studied by using photoluminescence (PL) spectroscopy at room temperature. The results show that the dislocation density and microstrain in the film were decreased by increasing annealing temperature for both anatase and rutile phases.
