摘要：

In this work, Ag doped In2O3 nanostructure materials were successfully synthesis using a simple hydrothermal process with different Ag concentration (3,6,9)%. The structural properties and morphology of the obtained nanostructure film are characterized by X-ray diffraction and field emission scanning electron microscopy (FE-SEM). The structural analysis shows a highly crystalline of indium oxide with a cubic phase and the crystallite size decreased with the increasing of doping concentration. The current-voltage results from devices indicate that In2O3 film with 9% Ag concentration has better conduction film. Gas sensing performance was studied for NO2 gas with different concentration (50,100,150) ppm at operating temperature 100 degrees C. The maximum sensitivity (S = 79 %) was found at doping concentration 9% Ag.
