Název v původním jazyce

Effect of gas environment on titania films microstructure characterized by emanation thermal analysis.

Popis výsledku v původním jazyce

Emanation thermal analysis (ETA), based on the measurement of the release of radon previously incorporated into the sample, was used to characterize the differences in the thermal behavior porous titania film (thickness 200 nm),when heated in argon and in oxygen, respectively, in the range from 20 to 800degreesC. It was observed that the annealing of porosity and structure defects in the near surface layers of the porous titania film (anatase) was enhanced on heating in oxygen in comparison to the heating in argon. ETA results were compared with SEM micrographs and XRD patterns of the titania film samples heated to 500 and 800degreesC, respectively. A mathematical model was used for the evaluation of the temperature dependence of the titania films microstructure development.
