Nanocrystalline of TiO2 thin films have been prepared by sol-gel dip coating technique. The problem is the TiO2 thin films have received considerable attention of phase crystallinity because of their potential applications and proven in certain areas. It has been discussed throughout the years based on the application devices. In this study, the TiO2 thin films were varied in different molarities...
TiO2 nanoparticles are prepared by sol-gel method. As revealed by X-ray diffraction (XRD) spectra the nanoparticles change their phase from anatase to rutile when the annealing temperature goes beyond 650°C. W-H plot for the powder samples annealed at 450°C and 750°C shows the presence of tensile strain in them which affects the particle size. The difference in particle sizes obtained from Debye-Scherer...
In this work, we have successfully prepared TiO2 thin films doped with various concentration of NbCl5. The doping concentrations were varied from 0.0 mol%, 0.1 mol%, 0.2 mol%, 0.3 mol% and 0.4 mol%. The characterizations were done by means of electrical properties and surface morphology. The results show that as the concentrations of NbCl5 increased, current escalates. For surface morphology, the...
Titanium dioxide, TiO2 is a semiconductor material which has many useful properties. This paper is to clarify the use of sol-gel method in the production of nanostructured TiO2. Since sol-gel method is quite simple to compare with sputtering or pyrogenic process. The solution concentration will be varied in low molarity of 0.06M, 0.04M and 0.02M. Spin coating was used to deposit the nanostructured...
Co (III) doped titanium dioxide (Ti1− xCoxO2) thin films with different Co volume ratios (x = 0.0, 0.05, 0.1, 0.15, 0.2) were successfully deposited using Sol-Gel route. X-ray Diffraction patterns revealed that the films were deposited with amorphous, anatase and rutile phases. These phases strongly influenced by annealing temperatures and doping profiles. By annealing at 500°C, the structure has...
Properties of a substrate play a very important role in determining the properties of nanostructures formed onto its surface. Optimizing the parameters of sol-gel, TiO2 nanostructures were synthesized on a pre-treated glass substrate by using hydrothermal method. Ten samples were prepared; each had a different thickness of TiO2 layer prepared by spin coating technique. After annealing was done, five...
Titanium dioxide thin films were prepared by sol-gel method on Si (110) substrates after annealed at 650 degC. Schottky diodes of Cr/TiO2, Au//TiO2 and Ni/TiO2 were fabricated by RF magnetron sputtering, and the electrical properties of the diodes were investigated. The effective barriers Phib and ideal factors n were calculated from thermionic emission model, and it was found that the height of Schottky...
