摘要
We fabricated oxygen sensors with thin films of single-phase cerium oxide prepared by metal organic chemical vapor deposition (MOCVD) and sputtering, and investigated the properties of both sensors. The response times of the thin films prepared by MOCVD and sputtering were about 9s when the films were heated to 888K for the first time. However, the response time increased each time, each sensor was heated to 1274K. The deterioration of the response time in this study seems to be related to increasing crystallite size. It was concluded that the thin film prepared by sputtering was suitable for oxygen sensors compared with that prepared by MOCVD.
