Effect substrate temperatures on the structural, morphology and optical properties of nanocrystalline TiO2 thin films prepared by PLD


Titanium dioxide is a wide band semiconductor which exists in three crystallographic phases: rutile , anatase and brookite. The first two polymorphs have a tetragonal symmetry and due to their strong photocatalytic properties and stability have become materials of high scientific interest. TiO2 nanostructures , as they significantly reinforce the photocatalytic properties of titanium , are commonly used in optical devices, self-cleaning protective coatings
