Tin oxide (SnO_2) nanostructures have been synthesized by a simple chemical route. The morphology and crystallization of the samples can be controlled by changing the mixed solution of tin chloride. The precursors were calcined at 600 °C for 2 h in air to obtain the SnO_2 nanorods and nanoparticles. The phase composition of the samples was investigated by XRD and electron diffraction analysis. The results confirmed the formation of a SnO_2 phase with tetragonal structure. The optical properties of the nanostructures were investigated by UV-vis spectroscopy. The estimated band gaps of nanorods and nanoparticles were 3.39 and 4.23 eV, respectively. The results revealed that the morphologies and band gaps of the samples varied with the mixed solution of tin chloride.
