摘要
The SnO2 content dependence of the sensitivity of sputtered SnO2-doped ZnO thin film chemical sensor is studied for various gases. It is found that the SnO2(78 wt%)-doped ZnO thin film chemical sensor exhibits a high sensitivity and good selectivity for C2H5OH gas. The sensitivity of the SnO2(78 wt%)-doped ZnO thin film chemical sensor responds to the freshness change of alcohols, indicating that the sensor is useful for freshness detection of alcohols.
