Abstract
This paper reports the effect of film thickness and curing temperature on the sensitivity of the screen-printed thick-film ZnO (incorporated with 7 wt%Sb) H-2, CO and CH4 sensors. The sensitivity of the sensors increases up to 60 mu m and decreases for higher film thickness. Incr ease in the curing temperature of the films, decreases the sensitivity of the sensors because of the increase in the average grain size, as observed by scanning electron microscopy.
