Nanostructured zinc oxide powder was prepared using the ultrasonic atomization technique. This powder was collected using simple indigenous glass trapping system attached to ultrasonic system. Thick films of this powder were prepared using simple screen printing technique. The films were characterized using XRD, TEM, SEM and EDAX to know structure, size of crystallites, microtopography and elemental analysis respectively. The conventional gas and simulants of chemical warfare agents sensing performances of these films were tested. The thick film sensor was found to be most sensitive to NH3 (conventional gas) and DMMP (simulant of chemical warfare agents) respectively. The results were discussed and interpreted.
