Growth and Characterization of SnO₂ Nanostructures by Vapor Transport Technique

Abstract:

Tin dioxides (SnO₂) nanostructure can be grown by vapor transport techniques through a vapor-liquid-solid (VLS) mechanism. The gas flowing have been effect on the evolution of various sizes and shapes of nanostructure materials. The crystalline structures of SnO₂ materials were investigated by X-ray diffraction (XRD) spectroscopy. XRD patterns of samples exhibited tetragonal phase. The characterization of synthesized products was performed by scanning electron microscopy (SEM). The controlling of process gas flow, showed the various kinds of nanostructures such as nanobelts, nanowires and nanobars of SnO₂. The Raman spectra of single-crystalline rutile SnO₂ nanostructures were studied, the vibration modes were observed corresponded to the typical feature of the SnO₂ nanostructure. A room temperature photoluminescence (PL) spectrum of SnO₂ material exhibited visible emission.
