Abstract
In this study, the gas sensing properties of SnO 2 and Zn 0.50 Sn 0.50 O samples produced by Succession Ionic Layer Adsorption and Reaction ( SILAR) method with different SILAR cycles against NO gas were investigated. Electrical characterization of the produced sample at different temperatures (35 °C-135 °C) and different gas concentrations (50 ppb-25 ppm) were performed. The working temperature was found at 105 ° C. The sensors were proved to have acceptable responses towards 50 ppb NO gas. Zn 0.50 Sn 0.50 O sensor exhibited improved sensing performance at working temperature of 105 ° C compared to SnO 2 sensor.. The ,responses of SnO 2 sensors for the 50 ppb NO gas concentration, sensitivities of 1.74%, 2.15% and 3.37% were obtained for 20, 30 and 40 cycles, respectively. On the other hand, the,responses of Zn 0.50 Sn 0.50 O sensors for the 50 ppb NO gas concentration sensitivities of 3.01%, 3.74% and 4.16% were obtained for 20, 30 and 40 cycles, respectively. The measurement results showed that the sensitivity of the sensors changed depending on the doping and producing cycles.
