Abstract
Cd1-xAgxIn2O4 (0.0 less than or equal to x less than or equal to 0.30) were synthesized with a chemical coprecipitation method. The phase constituents of Ag doped Cdln(2)O(4) materials were characterized by X-ray diffraction (XRD). Indirect-heating sensors were fabricated based on the materials. It is found that the Cd0.09Ag(0.10)In(2)O(4)-based sensor shows lower conducti vity and exhibits higher sensitivity to reducing gases and shorter response times than CdIn2O4-based sensor.
