Abstract

The vacuum-deposited thin film of hydrated tungsten oxide (WO₃•nH₂O) embedded poly(o-phenylenediamine) (PoPD/ WO₃•nH₂O) nanocomposite was fabricated on an indium tin oxide (ITO) coated glass surface for potential NO₂ gas sensor application. The resulting PoPD/WO₃•nHO/ITO thin film was characterized using ultraviolet-visible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FT-IR), X-ray diffractometry (XRD), and electron microscopy (SEM). The composite thin film exhibited a crystalline surface morphology containing nanocrystalls of WO₃•nH₂O with a diameter ranging from 5 to 10nm. The PoPD/WO₃•nH₂O/ITO film allowed for the low potential detection of NO₂ gas at concentration range from 0 to 1800 ppm. The NO₂ gas sensing characteristics were studied by measuring change in the current with respect to concentration and time. The current of the PoPD/WO₃•nH₂O/ITO film was linearly increased with an increase in concentration of NO₂ gas with a response of ∼9 s.
