摘要：
In this study, pristine and Fe-doped CeO2 nanoparticles (NPs) namely FexCe(1-x)O(2) (x = 0, 0.2, and 0.4) were synthesized through a facile chemical route. Different characterization techniques confirmed formation of NPs with desired morphology and chemical composition. Moreover, optical properties, bandgap, and functional groups were studied. The sensors were fabricated from the synthesized NPs and their relative humidity sensing was investigated. It was found that Fe0.4Ce0.6O2 revealed the best sensing properties where it showed a maximum response of similar to 83.94% to 100% RH, and its response and recovery times were 5 and 17 s, respectively.
