Nj. Dayan et al., EFFECT OF FILM THICKNESS AND CURING TEMPERATURE ON THE SENSITIVITY OFZNO-SB THICK-FILM HYDROGEN SENSOR, Journal of materials science. Materials in electronics, 8(5), 1997, pp. 277-279
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.
