thin films have a variety of applications, including electro-chromic displays, dye-sensitized solar cells, gas
sensors, antireflection films, planner wave guides and optical filters. It also has environmental applications,
being extensively used in the photo degradation of organic and inorganic pollutants, photovoltaic energy production
and the production of hydrogen by water photo splitting. TiO
2
is currently the leading photocatalyst because it
can mineralize a large range of organic pollutants. However, owing to its large band gap energy (typically <380
nm), TiO
2
can only absorb ultraviolet light but not visible light, which constitutes a proportion of solar light. The
overall quantum yield rate can be influenced by the low rate of electron transfer to dissolved oxygen and a high
rate of recombination between electron-hole pairs. The preparation of TiO
2
thin films has received great attention
because of its remarkable optical, photocatalytic and electrical properties. TiO
2
thin films have been prepared by
several techniques. In general, sol–gel methods are more flexible and offer many advantages. In this study, TiO
2
thin
films were prepared by the sol–gel method using the spin–coating technique because, nanocrystalline materials
have tremendous impact on various recent developments in industry and science. The annealing temperature plays
an important role during the crystalline process. The influence of the aged sol and annealing temperature on the
physical properties of TiO
2
thin films were investigated in this study.
