Abstract

The concise representation of conducted work: (a) EDAX, (b) ethanol sensing mechanism, (c) sensor response, and (d) SEM image of Dy: SnO nanoparti- cles. Key words: Dysprosium, tin oxide, ethanol sensor, thick films 12,13 INTRODUCTION sensing applications. The SnO gas sensors have several advantages such as high sensitivity, The detection of various gases with precise esti- low cost, reproducibility and stability. However, it mation of concentration finds a great deal of appli- has a major drawback, i.e., poor selectivity. To cations in several fields, such as domestic, medical improve the selectivity, many methods have been diagnostics, gas alarms, industrial worker safety, used, such as doping with metal/metal-oxides and environmental monitoring, defence fields and food noble metal catalysts such as Palladium (Pd), 1–6 industries. Ethanol is the most often used organic 14–19 Platinum (Pt) and Ytterbium (Yb). Previous material and, hence, is found in numerous large reports on rare earth doped SMO reveals that scale industries as manufacturer and supplier. In incorporation in SMO can eliminate several prob- view of safety concerns and protection, ethanol gas lems like poor sensitivity, response and higher sensors with not only detection but also precise working temperature.
