Abstract: Orthorhombic phase SnO2 is a material with unknown optical, electrical, and gas sensing properties. It was found previously only at high pressures and temperatures. Using pulsed laser deposition (PLD), this paper reports a kind of experimental realization of a pure orthorhombic SnO2 thin film under low pressure and temperature that are much lower than those of traditional methods. The optical properties of an orthorhombic SnO2 thin film were measured by spectrophotometric transmittance. An oxygen exchange reaction mechanism at the grain interfaces is proposed to explain the formation and optical properties of this orthorhombic phase.

Key words: orthorhombic, pulsed laser deposition (PLD), thin film, SnO2
