Electrical conductivity and gas sensitivity of Zn–Sb–O thick films

Abstract The thick film of Zn–Sb–O was prepared by coating the paste of nanoparticles mixture (Sb2O3:ZnO=1:3) on the alumina substrate, followed by sintering at 500–900 °C for 2 h in air. The electrical resistance and gas-sensing properties to benzene, alcohol and acetone of Zn–Sb–O films were found to be dependent on the change of phase structure caused by sintering temperature.
