title = "Effect of Ag2O Doping on the H2S Gas Sensing Properties of WO3Nanosensor",
abstract = "In this paper we report the synthesis and characterization of tungsten oxide doped silver oxide nanostructures. The effect of silver doping on the optical and sensing properties of tungsten doped silver oxide is studied and characterized for low-temperature H2S gas detection. Furthermore, we investigated the sensor response, electrical characteristics, response time of tungsten oxide (WO3) and tungsten oxide doped with silver oxide (Ag2O/ WO3) at different concentrations at 25°C. The study also presents the influence of the silver oxide doping of WO3 on the H2S based sensors performance in terms of sensitivity and response time. The obtained results proved the possibility of synthesizing tungsten oxide-based gas sensors for future H2S sensor devices. UV-VIS results reveal that doping WO3 with Ag2O enhanced the absorption of WO3 in the visible region which is indicated in the red shift. Furthermore, the sensing properties of WO3 is increased compared to bare WO3 and Ag2O which shoed no response to H2S in this temperature range. The electrical properties of WO3 also becomes ohmic as a result of Ag2O doping. The study illustrates a good way to improve the gas sensors performance through Ag2O doping.",
