Tin oxide (SnO 2 ) nanoparticles synthesized by hydrothermal method and kept at sintering temperatures (800-1200 ºC). The tin (II) chloride dehydrate (SnCl 2 .2H 2 O) used to prepared the SnO 2 precursor solution. The Tin oxide nanoparticles have been characterized by X-ray diffraction (XRD), Field emission scanning electronic spectroscopy (FESEM), and UV-Visible spectroscopy. The nanoparticles size of SnO 2 depends on the degree of sintering temperature, it found crystallite size (22.12,27.34 , 36.11 and 42.02) nm of the SnO 2 at800, 900, 1000 and 1200°C, respectively. XRD shows a pure tetragonal rutile crystalline structure for SnO 2 nanoparticles. FESEM images revealed the particles size increased with increasing sintering temperature. The transmittance and absorption are affected by an increased degree of sintering temperature. The band gap of SnO 2 nanoparticles decreased with increasing sintering temperature (2.6 to 2.4) eV when temperature raised from 800 to 1200 ºC, which belongs to the effect of particle size
