| Abstract(in English) | This paper is concerned with the Spray Pyrolytic (SP) deposition of various nanoarchitectures of electronically-conducting, F^--doped SnO_2 (FTO) on soda lime glass surfaces, and a possible mechanism for the growth of different nanoarchitectures including crystallites of nanoparticles, nanotubes, nanorods (nanopencils) and extensively cross-linked nanopencils. The spray pyrolytic deposition is carried out using a novel and purpose-built technique, known as the Atomized Spray Pyrolysis (APS), in which the precursor solution is withdrawn, using a programmed repetitive pulses of 2s on and 13s off, over different desired time periods, to an atomizer chamber, using a pressurized gas flow, where the precursor solution is incident on a Teflon spherule, in order to separate agglomerated particles into individual ones, which are in tern directed towards the pyrolytic chamber, maintained at 500℃. At the initials phase of the deposition, the nucleation of the FTO takes place on the glass surface to result in usual crystalline nanograins of FTO formed on the glass surface. As the deposition time is increased, the nanograins change to a hexagonal shape with a somewhat decreased crystallinity. For further increase, the deposition takes place on more reactive edge atoms/ions to result in nanotubes of hexagonal cross-section. Another deposition gradually fills the interior of the hexagonal columns to assume a shape of a rod and the filling continues further from the walls of the hexagonal tubes to give the shape of a pencil. Deposition of a total period of 3h results in vertically-aligned nanopencils with extensively cross-linked over layer of nanopencils on the vertically-aligned nanopencils. These nanostructured architectures formed are characterized using XRD, SEM and electronic conductivity measurements and the interesting results obtained are explained with a possible mechanism for the formation of different nanostructure-architectures by the same deposition method. |
