Abstrakt: Aqueous colloidal solutions of quantum sized particles of TiO2 undergo an ageing process beginning with their preparation. In course of time, the mean size of nanoparticles is gradually increasing and some of their physico-chemical properties are changing as well. In the present study, the decrease of the spectral blue shift of the semiconductor absorption threshold was measured to determine the corresponding changes of band gap energy of the Q-TiO2 particles.
