Abstract

An effective ammonia sensor was developed using a CsPbBr₃ thin film prepared directly by dual-source thermal evaporation. The CsPbBr₃-based sensor exhibited good selectivity toward ammonia gas at room temperature, showing a high responsivity (958% at 10 ppm) and low detection limit (250 ppb). The sensor also demonstrated good reversibility, repeatability and fast rise/recovery times (12/16 s). Additionally, the effect of humidity on ammonia responsivity was investigated for the application of CsPbBr₃ films in practical room-temperature ammonia gas sensors. The ammonia-sensing mechanism of the CsPbBr₃ film was proposed and discussed.
