Abstract

ZnO plate thick film gas sensors are fabricated by screen printing with self-prepared ZnO particles.Mg

Pd are doped into the sensors by micro-droplet doping. The gas sensitivities of the sensors to ethanol

acetone

benzene and acetic acid are measured. The results show that the micro-droplet doping is an effective way to improve the sensitivities and selectivity of the sensors. Among them

the Mg-doped sensor has the highest response values to ethanol and acetone

and the Mn-doped sensor shows better selectivity to acetic acid.
