- Abstract
SnO 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. 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 at different growth temperatures.
