Preparation of TiO₂ Thin Films by Sol-Gel Method and Analysis of its Transmittance Based on Computer Image Processing

Abstract:

TiO₂ films were prepared by sol-gel method with butyl titanate, anhydrous ethanol, acetyl acetone and hydrochloric acid as raw materials, which were sintered at 380 °C and 530 °C respectively to obtain TiO₂ films. XRD was used for analyzing the crystal structure of TiO₂ film, and ImageJ software was used to detect the light transmittance of TiO₂ film samples. The results show that the film sintered at 530 °C is brookite structure and the film sintered at 380 °C is anatase structure. The increase of sintering temperature is not conducive to the growth of TiO₂ film grains. TiO₂ films sintered at 380 °C have good light transmittance.
