Synthesis and characterization of undoped and Fe–doped SnO۲ nanoparticles

Tin oxide (SnO۲) nanoparticles have been successfully prepared using co-precipitation route using of tin chloride and sodium hydroxide as tin source and precipitating agent, respectively.  Fourier transform infrared spectrum, x-ray powder diffraction, scanning electron microscope, energy dispersive x-ray spectroscopy and transmission electron microscope were used to characterize as-prepared and heated samples. The broad XRD peaks were corresponding to small crystallitenanoparticles. Grain size of particles has been obtained around ۶ nanometers using XRD patterns and Scherer’s formula. SEM images were shown as rod morphology of nanoparticles and also a good monodispirsity of rods could be seen. The particle size was obtained less than ۲۰ nm using TEM images. Nice superparamagneticproperty was obtained when the samples were calcinated at ۲۰۰ °C. The particle size decreased as doping amount increased.
