Sputter deposited CuO-WO3 Nanostructures for Gas Sensing Application

Popis výsledku v původním jazyce

Combining two or more nanostructured materials is one of the propitious ways to improve the performance of towards various applications. In this work, we have synthesized a system of multiple nanostructured Metal-oxide Semiconductor (MOS) and used them further as conductometric gas sensors. We have prepared nanoclusters of cupric oxide (CuO) by a magnetron-based gas aggregation cluster source (GAS) on/under ultra-thin film of tungsten oxide (WO3). The combination of CuO nanoclusters and WO3 ultrathin film also leads to formation of nanolayer of a ternary oxide material, CuWO4.The sensing property of the prepared system is investigated towards various gases. The synergy of these materials significantly enhances the sensing performance for various gases. On the basis of characterization such as SEM, XRD, Raman, and sensing property, we propose that the sensing mechanism is based on the formation of multiple p-n and n-n type nano-junctions at the interface of CuO nanoclusters, CuWO4 and WO3 ultra-thin films.
