“…Tin oxide lms have been prepared by several methods such as chemical vapor deposition [9], spray pyrolysis [10,11], electron beam evaporation [12], sol gel [13] and sputtering [14]. Among the various deposition techniques, spray pyrolysis is well suited for the preparation of doped and undoped tin oxide thin lms because of its simple and inexpensive experimental arrangement, ease * corresponding author; e-mail: smrozati@guilan.ac.ir of adding various doping materials, reproducibility, high growth rate, and mass production capability for uniform large area coatings [15].…”

Nanostructured tin oxide (SnO2) thin lms have been prepared by spray pyrolysis technique. The eects of deposition conditions such as substrate temperature and tin chloride concentration in the precursor solution on physical properties of lms have been investigated. The physical characterization of samples was carried out by UV-VIS spectroscopy, X-ray diraction, scanning electron microscopy, and the Hall eect experiment for optical, structural, morphological and electrical studies, respectively. The lms are polycrystalline in nature with a tetragonal crystal structure. The preferred orientation has been changed by changing the deposition parameters. In the case of changing the substrate temperature, (211) was found as the preferred orientation, while by changing the molarities of the solution, (301) orientation was grown as well as (211). The deposition temperature was optimized to 450• C; whereas the optimum solution concentration was found to be 0.2 mol/L. Films deposited at foregoing conditions have good optoelectrical properties which make them suitable for applying in dierent optoelectronic devices.

ResumoFilmes de óxido de estanho com flúor, depositados sobre substratos transparentes, foram preparados a partir de uma solução contendo uma mistura de NH 4 F e SnCl 2 . Uma resistência cerâmica, inserida em um forno, foi usada como fonte de calor. A deposição foi feita por meio da técnica pulverização pirolítica, com vácuo sendo gerado no bico de pulverização. A caracterização das amostras foi feita com auxílio de microscopia eletrônica de varredura, espectroscopia UV-vis, resistência elétrica e difração de raios-X. Os resultados indicam a aplicabilidade do material para a aérea fotovoltaica. Palavras-chave:Óxido de estanho com flúor: Pulverização pirolítica: Vácuo. AbstRActFluoride-doped tin oxide films on glass substrate were prepared from NH 4 F-doped SnCl 2 precursor by spray pyrolysis with ceramic heater as heat source, which was inserted inside the reactor and created a vacuum within nozzle. The films were characterized by scanning electron microscopy, UV-Vis spectroscopy, measurement of electrical resistance and X-ray diffraction. The results showed that the fluoride-doped tin oxide films demonstrate potential as materials for photovoltaic applications.

“…The sputter deposition method has been usually utilized to fabricate the In:SnO 2 film with well-ordered dense structure, however the pore structure has not been formed during the deposition. On the other hand, sol-gel combustion method can be considered as a useful method for nanoporous structure fabrication process [6,7], and has advantages in efficient and large-scale fabrication of a nanoparticle electrode with large internal surface area. Until now, the sol-gel combustion hybrid method has been widely adapted to synthesize various nanoparticle materials, such as TiO 2 , F:SnO 2 and SnO 2 [6][7][8].…”

-Indium tin oxide (In:SnO 2 ) nanoparticles were synthesized employing a sol-gel combustion method followed by annealing. The TG, XRD, XPS and SEM results of the precursor powders and calcinated In:SnO 2 nanoparticles were investigated. Crystal structures were examined by powder XRD, and those results show shaper intensity peak at 25.6° (2θ) of SnO 2 by increased annealing temperature. A particle morphology and size was examined by SEM, and the size of the nanoparticles was found to be in the range of 20~30nm. In:SnO 2 films could controlled by nanoparticle material at various annealing temperature. The sol-gel combustion method was offered simple and effective route for the synthesis of In:SnO 2 nanoparticles.
