Abstract: In2O3 has been doped in ZnFe2O4 by a chemical coprecipitation method. XRD results showed that in doped system there is no new phase formed and only a little change in lattice constants. Doping of In2O3 decreased the conductivity of ZnFe2O4 sensor, changed its conduction mechanism and increased its response to C2H5OH.

Key words: ZnFe2O4, In2O3, doping, ethanol sensor
