Sažetak
Nanosized TiO2, 1 μm thick, films on glass substrate were prepared using chemical vapour deposition (CVD) and spray method procedure. The average grain size < R > , obtained by grazing-incidence small-angle scattering of synchrotron radiation (GISAXS) varied with the annealing temperature (500 to 900 °C in H2, O2 and N2) for the CVD prepared samples. For TiO2 films obtained by the spray method, < R > increased with annealing temperature from 4.2 to 7.2 nm. Specific surface areas of both films were also determined and varied from 0.18·107 to 3.2·107 cm-1.
