SnO2 ∶Ti thin film of different doping concentrations are prepared by sol-gel and tested by XRD.The gas sensing optical properties of the film in the ethanol are researched at the room temperature.The experimental result shows that response time of SnO2 ∶Ti thin film is significantly shorter than the other at the room temperature and is related to doping concentrations.Sensitivity of 10% SnO2 ∶Ti film at the range of 1800
