The thin films of TiO2 were prepared by the Sol-Gel, on glass
subtracts by using the following initial solutions: trichlorethylene
titanium, ethanol, sodium hydroxide and hydrochloric acid and
distilled water. The films were annealed at temperatur
es(200- 300-
400-500)c° for 1 hour. The structure of the prepared and annealed
films were studied by XRD. The XRD rusltes showed that the films
prepared crystallize according to orthorhombic Structure.Lattice
constants were calculated and it was found that it was consistent
with the data JPCDS and with some scientific works.
