In the presented research article, track radii of swift heavy ions against electronic stopping power have been estimated using thermal spike model. The time evolution of lattice temperatures at several different values of track radii in anatase TiO2 film irradiated with 100MeV O(16), 100MeV Si(28), 100MeV Ni(58) ions have been predicted. Study of track radii can help to optimize the porosity of the film which is a major efficiency governing factor in dye-sensitized solar cells. It has been observed that radius of lattice temperature over the melting point of anatase TiO2 lie very close to the radius of the stressed region.
