Zusammenfassung:Thick films of AR Grade nano Fe 2 O 3 material with n-type semiconducting properties were prepared and tested for their gas sensing performances. Thick films of the materials were prepared by screen printing technique. The gas sensing performance was studied using static gas sensing system. The material was tested for various gases such as CO, CO 2 , NH 3 , Cl 2 , H 2 , LPG, ethanol and H 2 S. The nano Fe 2 O 3 film showed maximum sensitivity to ethanol gas at 350 °C temperature at 250 ppm concentration with short response time and large recovery time. Physical and structural properties of the film material were studied by SEM, TEM, XRD and UV spectroscopy.
