Fabrication of transparent titanium dioxide thin film at low temperature by Sol-gel Spin Coating Method
Titanium Dioxide (TiO2) thin film with various sol-gel concentrations has been successfully prepared using sol-gel spin coating method. The preparation of the TiO2 thin films was prepared at room temperature. The electrical and optical properties were characterized using 2- point probe I-V measureme...

| தொகà¯à®ªà¯à®ªà¯: | Titanium Dioxide (TiO2) thin film with
various sol-gel concentrations has been
successfully prepared using sol-gel spin coating
method. The preparation of the TiO2 thin films
was prepared at room temperature. The electrical
and optical properties were characterized using 2-
point probe I-V measurement and UV-Vis-NIR
Spectrophotometer. For electrical properties, 0.2M
of sol-gel concentration gives the lowest sheet
resistance among other concentrated sol-gels. The
optical transmission in the visible region (450–
1000 nm) for 0.1M and 0.2M are the highest
(>80%), indicating that the films are transparent in
the visible region. The transmission decreases
sharply near the ultraviolet region due to the band
gap absorption. The prepared TiO2 thin film can
be used in many applications such as solar cell
application, sensors and Ultra Violet coatings. |
