SnO Nanostructures: Effect of Processing Parameters on Their Structural and Functional Properties.

Zero- and 1D (one-dimensional) tin (IV) oxide nanostructures have been synthesized by thermal evaporation method, and a comparison of their morphology, crystal structure, sorption properties, specific surface area, as well as electrical characteristics has been performed. Synthesized SnO nanomaterials were studied by X-ray diffraction, scanning and transmission electron microscopy (SEM and TEM), N sorption/desorption technique, IR spectroscopy and, in addition, their current-voltage characteristics have also been measured. The single crystalline structures were obtained both in case of 0D (zero-dimensional) SnO powders and in case of 0D nanofibers, as confirmed by electron diffraction of TEM.

Synthesis and Characterization of Tin(IV) Oxide Obtained by Chemical Vapor Deposition Method.

The effect of precursors on the characteristics of tin oxide obtained by chemical vapor deposition (CVD) method was investigated. The synthesis of nanosized tin(IV) oxide was carried out with the use of two different precursors: tin(II) oxalate obtained using tin chloride(II) and oxalic acid; tin(II) oxalate obtained using tin chloride(II); and ammonium oxalate. The synthesized tin(IV) oxide samples were studied by electron microscopy, X-ray diffraction and optical spectra.
