摘要：
SrFeO2.97 phase obtained by annealing radiofrequency-sputtered stoichiometric film at 600A degrees C for 24 h has been tested using a homemade apparatus coupled with impedance spectrometry. Oxygen nonstoichiometry plays a vital role in sensing of reducing gases. Hence, this phase showed efficient sensing performance for different reducing gases such as acetone (CH3COCH3), ethanol (C2H5OH), ammonia (NH3), and hydrogen sulfide (H2S), with high sensing response recorded for H2S gas at 60A degrees C.
