“…Therefore, TiO 2 thin film fabrication is continuously conducted to obtain better film characteristics. Several methods used in the synt-hesis of TiO2 are sol gel methods [3,4], solvotermal [5], thermal decomposition [6] and hydrothermal [7][8][9]. The hydrothermal method has the advantage of simple preparation, relatively low reaction temperature, uniform dispersion for metal ion doping, as well as stoichiometric control and provides good homogeneity [10][11][12] although method usually proceeds for a relatively long time (~ 10 h).…”

Titanium dioxide is used extensively as semiconductor since more than five decades. Hydrothermal method is one the method which widely used for the synthesis of TiO2 have been widely developed. The effect of hydrothermal temperatures on the titanium dioxide films is investigated. The TiO2 films were prepared by hydrothermally layering a mixture of aquadest, HCl and titanium(IV) isopropoxide over indium tin oxide glass, at 110, 150, 180 and 200 ºC for 10 h. The film on the surface of indium tin oxide glass was calcined at 500 ºC and characterized by X-ray diffraction, UV-visible spectroscopy and scanning electron microscopy-energy dispersive X-ray (SEM-EDX) methods. The study shows that the TiO2 has a spherical morphology with the size between 0.5 to 2 µm. The TiO2 consits of rutile and anatase with the particle size ranging from 16.97 to 24.10 nm and from 18.09 to 26.75 nm, respectively. The band gap energy of TiO2 is between 3.17 to 3.48 eV.This is an open access journal, and articles are distributed under the terms of the Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0) License, which allows others to copy and redistribute the material in any medium or format, remix, transform, and build upon the material, as long as appropriate credit is given and the new creations are licensed under the identical terms.
