Mo Dopant Concentration Effect on Nanostructured WO<sub>3</sub> Thin Films Grown by Spray Deposition Surface Properties
The present communication reports on the effect of Mo dopant concentration on nanostructured WO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> thin films deposited by spray deposition surface properties. Monoclinic Mo doped WO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> thin films were obtained by spray deposition method for further integration in gas sensors. Mo-doped WO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> thin films are expected to have enhanced gas sensing properties, particularly for reducing gases like hydrogen (H2) and nitrogen dioxide (NO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>). The improved performance is due to the increased surface area, enhanced conductivity, and modified surface chemistry facilitating gas adsorption and reaction. The optimal doping concentration balances increased active sites and electronic properties without excessive defect formation. Further studies are ongoing.
