Purpose: The article presents the results of research on titanium dioxide synthesized by
a sol-gel method that is an easy process enabling the control of the shape and size of
particles The purpose of this article is to examine titanium dioxide nanoparticles and thin
films deposited by an atomization method.
Design/methodology/approach: Titanium dioxide sol was synthesized by using titanium
isopropoxide as a precursor. Optical properties were measured by a UV-Vis spectrometer.
Structural studies were performed by Raman spectroscopy. Qualitative analysis was
performed by the EDS. Surface morphology of nanoparticles and thin films was performed
by the SEM technique.
Findings: The sol-gel method allows the formation of uniform nanoparticles and thin films
of titanium dioxide. The atomization method is a successful method for the deposition of sol
to the surface of substrates.
Research limitations/implications: The next step in the research will be to investigate
the obtained thin films in dye-sensitized solar cells as a semiconductive layer.
Practical implications: Unique properties of produced titanium dioxide nanostructural
materials have caused the interest in them in such fields as optoelectronics, photovoltaics,
medicine and decorative coatings.
Originality/value: Titanium dioxide thin films and nanoparticles were synthesized using
the sol-gel method and then deposited by the atomization method.
