The Properties of WO 3 Based Gas Sensitive Films Prepared by Electron Beam Evaporation
【摘要】 介绍了用电子束蒸发制作WO3气敏薄膜、溅射掺Au、膜的热处理工艺以及对H2S气体的敏感特性测量的初步结果.着重讨论了WO3膜的稳定化过程.
【Abstract】 The WO 3 based gas sensitive films were prepared by electron beam evaporation. The D.C. sputtering technology used to dope Au, the heat treatment of the films, and preliminary test results of the sensitivity characteristic of H 2S gas are described. The process of stabilization of the structure and the composition of films is discussed.
