Characterization of TiO2 Nanofilms Obtained by Sol-gel and Anodic Oxidation
The influence of sol-gel dip-coating and anodic oxidation process parameters in producing thin TiO2 films is studied. As the size of the films is in the order of nanometres (20-140 nm), to obtain a precise measurement of their thickness and analyse their crystalline structures, glancing incidence an...

| description | The influence of sol-gel dip-coating and anodic
oxidation process parameters in producing thin TiO2 films is
studied. As the size of the films is in the order of nanometres
(20-140 nm), to obtain a precise measurement of their
thickness and analyse their crystalline structures, glancing
incidence angle X-ray techniques (X-ray reflectometry and Xray
diffraction) using synchrotron radiation are used. A
relationship between the colour and thickness of the films
was found. This enables the film thickness to be estimated by
the film colour. Within the range of the parameters studied,
both techniques produce thin films with smooth surfaces
which at most reproduce the roughness of the polished
substrate. Independently of the technique, thermally-treated
films thicker than 30 nm presented different crystalline
structures with anatase and rutile phases. |
