“…Moreover, the preferred orientations depend on compounds' source, solvent and growth parameters such as solution and deposition concentration [7,19,20]. The crystallite size (D) of these AFTO thin films is calculated using Debye-Scherrer's formula, D=0.9λ/(βcosθ) [8] where λ is the wavelength (λ=1.5418 Å), β means of the broadening of diffraction line measured at (FWHM) and θ is the Bragg angle. Structural parameters of these AFTO thin films which were calculated for only preferential orientation plane by using above formula are summarized in Table 1.…”

“…Transparent on optical range, low resistivity conducting and wide optical band gap (Eg) (>3 eV) oxides (TCOs) have attracted the scientists due to their wide using in many research and industrial areas for example, lowemissivity glass [1], window defrosters [2], transparent anode layer for all general organic light emitting diodes [3] and optoelectronic devices [4][5] gas sensor [6], DSSC solar cell [7] and flat panel TV displays. This combination sort of transparency and conductivity isn't usually possible in intrinsic stoichiometric oxides; however, it is made in a non-stoichiometric composition or with appropriate dopants as Sb, F, Zn, Mo, Pr and Ta [8]. So, from 1940 year to nowadays many studies on TCOs by using different methods and by changing the conditions required to prepare them have been making to improve properties of them [1][2][3][4][5][6][7][8][9].…”

“…Whenever depositing, an O 2ion is substituted with an Fion and donor level is produced. Also, Sb introduces Sb 5+ ions that act as donors but after that Sb 3+ ions begin to replace the Sn 4+ ions [8,10,11]. So, doubly doped process can be made.…”

Doubly (antimony and fluorine) doped tin oxide (SnO2:Sb:F/AFTO) thin films with low solution concentration and low Sb doping were deposited on the glass by using spray pyrolysis technique at different substrate temperatures. The effect of substrate temperature on properties of the prepared films was investigated. It was seen from X-ray diffraction analysis that the thin films are rutile structure with polycrystalline and orientations along (101), (200) and (210) directions for all substrate temperature. SEM and AFM images indicated that thin films were affected by substrate temperature and the surface of films was homogeneous and to be made of nanocrystalline. The films have 83% average transmittance values and Eg values are between 3.10-3.89 eV. These Eg and transmittance values changed continuously with substrate temperatures. Hence, it was concluded that properties of thin films were affected by the substrate temperature and these result mostly compatible with the results obtained from literature.
