摘要：Titanium dioxide(TiO2)thin films were synthesized via sol-gel spin coating method using titanium tetraisopropoxide (TTIP) as starting material. TTIP is dissolved in ethanol stabilized by glacial acetic acid. TiO2 thin filmswere prepared for different proportions of acetic acid. The prepared samples were dried at 250°C for 5minutes thenannealed at 500°C for 1hr. The structural properties were investigated by using X-ray diffraction technique and grainsize was calculated. Elemental analysis and surface morphology were studied using EDX spectrum and SEMmicrograph. Absorbance spectra were measured by using UV-Vis spectrophotometer and the optical band gap wascalculated. The crystalline size of TiO2 thin films obtained is ~19.67nm.
