摘要：
Multiferroic perovskite bismuth ferrite is synthesized by a co-preparation method here and characterized by Xray diffraction(XRD), diffused reflections spectroscopy(DRS), scanning electron microscopy(SEM) and transmission electron microscopy(TEM) analysis. Clad modified fiber optic gas sensors made from BFO nanopowder demonstrate good sensitivity to ethanol gas at room temperature. Gas sensing behavior of this material to various concentration of ethanol in 0 ppm, 100 ppm, 200ppm and 300 ppm has been studied. Results reveal that nanoparticles BFO has the highest sensing to 300 ppm with a response and a recovery time of 10.5 and 20.3 min, respectively.
