Abstract—TiO
2 nanoparticles were prepared at room temperature by sol-gel method. In the current work, different surfactants such as Acetic Acid (AA), Oleic Acid (OA), and Oley amine (OM) were used for the preparation o
f TiO
2 nano
particles. TiO
2 powder was collected by centrifuging precipitation obtained during gel formation. The powder was thoroughly cleaned few times in ethanol and annealed at 550
o C and 950
o C at specific time. I-V measurement is used to inve
stigate the electrical properties of TiO
2 pallets. In order to elucidate the influence of using these surfactants, the structural and optical properties of powder were investigated by means of X-ray diffraction (XRD), U-v visible, and Photoluminescence (PL). It was found that annealing could improve the crystallization of TiO2 powders and accelerated the phase transformation from anatase to rutile phase but surfactants do not change the particle size and energy band gap of titania.
