Excellent acetone sensing property with high selectivity and long-term stability has been observed in single phase crystalline bismuth ferrite (BFO) nanoparticles. This phase pure BFO nanoparticles were synthesised via a simple sol-gel method and well characterized using various sophisticated instruments. BFO nanoparticles exhibit remarkable response (S = 1.8) towards 1 ppm of acetone at an operating temperature of 350 degrees C. The prepared sensor is extremely selective towards acetone among different gas analyte and also insensitive to moisture which can be attributed to a particular operating temperature (350 degrees C). Additionally, other important features of the sensor include high reproducibility and long-term stability for around 1 year. Displayed efficient sensing performance of these BFO nanoparticles-based sensors could be a potential candidate for different application e.g non-invasive monitoring of diabetes.
