Evolution of anatase phase for the TiO₂ nanocrystals at their laser irradiation is
researched by the method of combinational light dispersion. The observed changes of
intensity, frequency and halfwidth of TiO₂ phonon lines are interpreted taking into
account the effects of nonstoichiometry, superficial strains and phonon confinement. The
found out parameter changes in the low frequency Eg mode show that laser irradiation
results in substantial improvement of the structural ordering in the area of TiO₆
octahedrons bonds.
