The prepared fluorine
doped TiO2 was smaller in size with respect to pure TiO2 and it is tetragonal in crystalline structure.
Nanoflakes like structure of pure and fluorine doped TiO2 was confirmed from SEM image. Fluorine doped
TiO2 shows smaller band gap, high strain and dislocation density when compared to pure TiO2. It also has
higher photocatalytic activity with respect to pure TiO2.
