SnO2∶ Ti thin film is prepared by sol-gel method.SnO2∶ Ti thin film of three different mass fractions(5 %
10 %
15 %)are prepared during the preparation process.The gas-sensing optical properties of the film in the acetone atmosphere and methane atmosphere are researched at the room temperature.The results show that SnO2∶ Ti thin film has different responses for different test gas and is related to doping quantities.Mass fraction of 5 % SnO2∶ Ti thin film in the acetone atmosphere remains at 13 % at the range of 1 300
2
500 nm wavelength.Mass fraction of 15 % SnO2∶ Ti thin film in the methane atmosphere remains aroud 7 % at the range of 1 700
