摘要：
The gas sensing optical characteristic of La doped SnO2 film was studied. The transmission spectrograms of the film in alcohol and ammonia gas were recorded. It shows that the gas sensing sensitivity of the film to alcohol is increased, and the selectivity is improved. The theory of splitting energy state of solid surface is used to explain the gas sensing mechanism.
