Abstract
In this
study , tin oxide (SnO 2 ) films were deposi ted on 480°C heated glass by spray
pyrolysis with moving nozzle SPMN )). Tin chloride (SnCl 2 , 2H 2 O) was used as
precursor solution, iron chloride (FeCl 3 ) and lithium chloride (LiCl 2 ) were used as
doping sources. Effect of high/low Fe and Li doping concentration on structural,
morphological, optical, and electrical properties of SnO 2 thin films. The t ransmittance
of all Fe doped SnO 2 thin films was more than 78% in the visible region. The o ptical
gap was found to be in 3.64 3.58 eV. The ex istence of functional groups and the
chemical bonding is confirmed by Fourier transform infrared spectroscopy (FTIR)
spectra. X ray diffraction study showed that elaborated thin films have a
polycrystalline structure with tetragonal crystal. The preferenti al orientation shift from
211 ) toward 110 ) plane for 1, 2 and 4 wt.% Fe/Sn only, whereas crystalline size was
ranged in 57 36 nm. An increase in electrical resistivity increases from 1.2×10 4 to
3.4×10 3 Ω cm. The Hall effect measurements have shown n type for non doped SnO 2
thereafter the type conductivity changes to p type for more than 2wt.% Fe doped
SnO 2 thin films.
