Abstract: The bilayer film consistetl of α-Fe2O3 and SnO2 was prepared by the sputteringmethod. The film showed a better sensitivity and selectivity than the individual layer alone.The effects of heat treatment conditions and thickness of the α-Fe2O3 layer on the gas-sensingproperty of the product have been studied.

Key words: α-Fe2O3, SnO2, bilayer film, gas-sensing property
