摘要: SnO2是重要的气敏传感材料,采用纳米技术,可使元件微型化、集成化,并可提高灵敏度.

关键词: 气敏薄膜, 表面掺杂, 催化

Abstract: By doping Ag on the surface of the SnOx gas sensing film, the sensitivity and selectivity are improved greatly, and the working temperature is decreased. The catalysis of Ag has been discussed based on the color change of the film during measuring procedure.

Key words: gas sensing thin film, surface doping, catalysis
