Abstract

In this work, double activation of the optimal thickness of Ag NPs/WO_2.72/Au NPs thin films have been fabricated by DC sputtering followed by thermal annealing treatment for ammonia gas sensing applications. The effect of WO_2.72 thickness on the response level and optimum working temperature of Ag NPs/WO_2.72/Au NPs sensors is explored and compared with that of Ag NPs/WO_2.72, and WO_2.72 films. The results obtained in this work demonstrate that the response to 100 ppm ammonia of Ag NPs/WO_2.72/Au NPs was 84%, which was twice and seven times higher that of Ag NPs/WO_2.72 and pure WO_2.72, respectively.
