Effect of spray conditions on formation of one-dimensional fluorine-doped tin oxide thin films

This paper describes the preparation and characterization of optically-transparent thin films of fluoride-doped tin oxide (FTO) nanoparticles, nanotubes and nanorods grown using purpose-built, novel and advanced version of spray pyrolysis technique, known as Rotational, Pulsed and Atomized Spray Pyrolysis. Uniform and crack-free FTO1-D nanostructured thin films over 50 mm × 50 mm soda lime glass substrate have been routinely achieved. This technique allows a perfect control of morphology of nanostructures of FTO layer simply by adjusting the spray conditions. Formed 1-D FTO nanostructures on the glass substrate show an excellent optical transparency in the visible light range. XRD (x-ray diffraction) and SEM (scanning electron microscope) data show excellent correlations.
