摘要：
In this work, Undoped ZnO and Fe-doped ZnO nanostructures were successfully synthesized by using the simple hydrothermal method and their structural, morphological by various characterization techniques and studied the gas sensing properties. The Field emission electron microscopy (FE-SEM) observed that the nanorods assembled together to form the flower like in undoped ZnO and after Fe doping it turns into nanoellipsoid like morphology. NO2 gas response analysis revealed that Fe-doped ZnO nanoellipsoids displayed a higher selectivity compared to undoped ZnO. Among the different doping concentration 8 wt% exhibited the highest response of 209.8 when exposed to 100 ppm concentration of NO2.
