K. Shimizu et al., Low-temperature synthesis of anatase thin films on glass and organic substrates by direct deposition from aqueous solutions, THIN SOL FI, 351(1-2), 1999, pp. 220-224
Crystalline titania thin films were obtained on glass and various kinds of
organic substrates at 40-70 degrees C by deposition from aqueous solutions
of titanium tetrafluoride. Transparent films consisting of small anatase pa
rticles (similar to 20 nm) exhibited excellent adhesion to relatively hydro
philic surfaces. Uniform coatings were successfully prepared on substrates
with complex shapes such as cotton and felt fiber, Growth rate and particle
size were controlled by both the deposition conditions and the addition of
an organic surfactant. Organic dyes were incorporated into the anatase fil
ms using organic-dye dissolving solutions and a surfactant. The photo-catal
ytic property of the titania films deposited in the precursor solutions at
relatively low temperatures was identified as that of thermally crystallize
d anatase. (C) 1999 Elsevier Science S.A. All rights reserved.
