Abstract

Thick films of pure and CuO-modified SrTiO3 (STO) were prepared by screen printing technique. The prepared films were fired at 500o C for 30 min. The mechanochemically synthesized STO powder sintered at 800o C were used for preparation of thick films. The STO films were modified by dipping technique. Pure and modified STO thick films were tested for various gases. The maximum gas response (1225) was obtained for CuO dipped STO thick film (dipping time = 20 min and firing temperature = 300o C). The CuO modification has significant effect on sensing performance. The instant response T25 and fast recovery T45 are main features of sensor. The par-ticle properties were analyzed by SEM and EDS analysis. Selectivity, response recovery times were investigated and discussed.
