[Gas-sensing transmittivity spectrum of two-dimension SnO2: TiO2 compound film in ammonia vapor].
In this paper, we studied the gas-sensing transmittivity spectrum of the two-dimension SnO2: TiO2 compound film in ammonia vapor. It was observed that when the gas concentration was relatively low the transmittivity decreased as the gas concentration decreased, and when the gas concentration was relatively high, the transmittivity increased as the gas concentration increased. We considered the effect of the wet vapor, and explained this phenomenon.
