Characterisation and Evaluation the Effects of GeO2 and SiO2 Doped TiO2 Thin Films

摘要

TiO2 films have been prepared and doped with different ratios of GeO2 and SiO2. The effects of dopant ratio as well as the Thymol blue dye on the structural and optical properties have been investigated using XRD, FTIR and UV-visible absorption spectra. Results revealed that such dopant has great effects on the TiO2 lattice and structure which in turn induce the optical band gap of the films.
