Phase transformation in semi-transparent TiO2 films irradiated with CO2 laser

Anatase (TiO2) thin films were obtained by immersion of glass plates into a titanium sol-gel precursor followed by calcination at 450 degree C for 3h. The Raman results for the CO2 laser irradiated TiO2 films show that laser radiation is able to promote favorable changes of anatase phase in anatase/...

Zusammenfassung:Anatase (TiO2) thin films were obtained by immersion of glass plates into a titanium sol-gel precursor followed by calcination at 450 degree C for 3h. The Raman results for the CO2 laser irradiated TiO2 films show that laser radiation is able to promote favorable changes of anatase phase in anatase/rutile mixtures. Nevertheless, the transformation process level depends on laser characteristics and scan speed of the radiation treatment.
