摘要：

Tin salt precursor capped by oleic acid under solvothermal conditions gives tetragonal rutile phase of SnO2 with average particle size of 14 nm with a band gap of 4.27 eV. The SnO2 nanoparticles exhibit photoluminescence with an intense purple emission band at 425 nm. The transmission electron micrographs show the growth of nanoparticles in specific orientation. The petroleum gas sensing response of this material decreases with increase of sensing temperature.
