“…They not only provide a good system to study the electrical and thermal transport in one-dimensional confinement, but also are expected to play an important role in fabricating electronic, optoelectronic, and magnetic storage devices with nanoscale dimension (Xia et al 2003). Tin oxide is an important functional material, which has been widely applied in the field of opto-and microelectronics, such as solar cells (Ferrere et al 1997), transparent conducting electrodes (He et al 1993), gas sensors (Ansari et al 1997;Varghese and Malhotra 1998), and transistors (Duan et al 2001). The synthesis and assembly of 1D SnO 2 nanostructures such as wires and belts have attracted great interest due to their unique applications in gas sensors and field-effect transistors (Comini et al 2002;Kolmakov et al 2005;Dattoli et al 2007).…”

SnO 2 nanowires and nanobelts have been grown by the thermal evaporation of Sn powders. The growth of nanowires and nanobelts has been investigated at different temperatures (750-1000°C). The field emission scanning electron microscopic and transmission electron microscopic studies revealed the growth of nanowires and nano-belts at different growth temperatures. The growth mechanisms of the formation of the nanostructures have also been discussed. X-ray diffraction patterns showed that the nanowires and nanobelts are highly crystalline with tetragonal rutile phase. UV-visible absorption spectrum showed the bulk bandgap value (~ 3⋅6 eV) of SnO 2 . Photoluminescence spectra demonstrated a Stokes-shifted emission in the wavelength range 558-588 nm. The Raman and Fourier transform infrared spectra revealed the formation of stoichiometric SnO 2 at different growth temperatures.

“…Tin oxide has excellent physical and chemical properties when the particle size or grain size is reduced to nanometer scale. The nanocrystalline SnO 2 is considered as a key material for photovoltaic device [1], transparent conductive electrode [2], gas sensor [3,4], and anode materials of secondary lithium battery [5].…”

“…Among many semiconductor materials, tin oxide, a prototypical transparent n-type semiconductor with a wide band gap (Egap = 3.6 eV at 300 K), possesses interesting optical, dielectric, and catalytic properties. This has resulted in many industrial applications, such as catalyst support, transparent conducting electrodes, and gas sensor [38,39]. This material has advantages, including high thermodynamic stability in air (at least up to 500°C), low cost, and a possibility of introducing catalysts or dopants to enhance the sensitivity or selectivity [40].…”

A new tin complex, [l-(4-bpdb){Me 2 Sn(cupf) 2 } 2 ] (1), was prepared by reacting dimethyltin(IV) dichloride, with 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene (4-bpdb) and cupferron in a fast and facile process. The complex was fully characterized based on its 1 H and 13 C NMR, IR, and UV spectra and elemental analysis. The nanostructure of the prepared compound was synthesized by the sonochemical method. The new nanostructure was characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), IR spectroscopy and elemental analysis. Thermal stability of single crystalline and nanosize samples of the prepared compound was studied by thermal gravimetric and differential thermal analysis. The prepared complexes, as bulk and as nanoparticles, were utilized as a precursor for preparation of SnO 2 nanoparticles by direct thermal decomposition at 600°C in air. The morphology and size of the SnO 2 nanoparticles were determined by scanning electron microscopy, XRD and IR spectroscopy and the results showed that particle size of the SnO 2 nanoparticle depend on the initial particles size of 1. Photoluminescence properties of the nanostructured and crystalline bulk of the prepared complex and SnO 2 nanoparticles core of them were investigated.
