چکیده انگلیسی
This work reports the chemical spray synthesis of bismuth ferrite (BiFeO3, abbreviated as BFO) and tungsten-doped bismuth ferrite (W-BiFeO3, abbreviated as BWFO) nanostructured films and their nitrogen dioxide (NO2) and hydrogen (H2) gas sensor applications. The influence of tungsten-doping on the structure, morphology, surface area, and the characteristics towards NO2 and H2 gas sensing of BFO has been studied and explored and also compared with pristine BFO. The W-doping in BFO, confirmed by X-ray diffraction, energy dispersive X-ray and Fourier-transform infrared spectroscopy measurements, is proposed to explain the relative improvement in gas sensing performance between BFO and BWFO nanostructured films. At dilute concentration (100â¯ppm) of NO2 and H2, BWFO displays an enhanced sensitivity over BFO, which is attributed to specific changes in the morphology, structure and surface area.
