The effect of Fe2O3 doping on the gas sensitive properties of In2O3-Ga2O3 composition

Abstract

The sensitivity of nanocomposites In2O3:Ga2O3 (98:2, 96:4, 92:8 wt.%), both pure and doped with Fe2O3 (0,5-10 wt.%), has been investigated. Nanocomposites In2O3:Ga2O3 have been obtained by the sol-gel method, Fe2O3 has been obtained by various methods of Fe (II) and Fe (III) salts deposition. Standart gas mixtures contained 5000 ppm CH4 in air, 5000 ppm CO in air, as well as 2 and 10 ppm NO2 in nitrogen. The possibility of selective detection of NO2 over CH4, CO, ethanol vapor and other volatile organic compounds at low sensor power consumption (200 mW) has been established.
