Nanostructured Materials Based on Thin Films and Nanoclusters for Hydrogen Gas Sensing

Popis výsledku v původním jazyce

In this paper, we present two approaches of forming nanostructured metal oxide semiconductors in a form of multi-layer thin films. Films were then tested as conductometric gas-sensors. First approach is a combination of thin solid film of tungsten trioxide (WO3) with nanoclusters of cupric oxide (CuO) prepared by magnetron-based gas aggregation cluster source. The second method is a two-step sequential reactive magnetron sputtering forming a nanostructured copper tungstate (CuWO4) on-top of WO3 film. Both methods lead to formation of nanosized hetero junctions which greatly improves the sensorial response to hydrogen in comparison with WO3 thin film alone.
