Abstract
In this paper, stable water solution using a Pechini sol-gel process was prepared. The solution was used for the direct printing of iron oxide precursor on alumina substrates. To convert the precursor to the desired iron oxide phase, an annealing step was carried out at elevated temperatures (>450 °C). In this work a α-Fe2O3 thin film-based chemoresistive sensors for ethanol detection in air were fabricated. The device developed was investigated for evaluate the sensing characteristics such sensitivity, selectivity and stability. © Springer International Publishing AG 2018.File in questo prodotto:
