Abstract

Herein, we report the effect of the laser illumination during the diffuse-reflectance laser-flash-photolysis measurements on the morphological and optical properties of TiO 2 powders. A grey-blue coloration of the TiO 2 nanoparticles has been observed after intense laser illumination. This is explained by the formation of nonreactive trapped electrons accompanied by the release of oxygen atoms from the TiO 2 matrix as detected by means of UV-vis and EPR spectroscopy. Moreover, in the case of the pure anatase sample a phase transition of some TiO 2 nanoparticles located in the inner region from anatase to rutile occurred. It is suggested that these structural changes in TiO 2 are caused by an energy and charge transfer to the TiO 2 lattice.
