Development of Hybrid Perovskite MAxFA1-xPbI3 Fluorescent Sensor for the Monitoring of Ammonia Microconcentration
摘要
In this research, the optical properties and gas sensitivity of the MAxFA1-xPbI3-based perovskite material were used to detect ammonia gas at low concentrations. The resulting optical sensor exhibits relatively strong and stable photoluminescence intensity and extends the luminescence response range for ammonia gas detection. It showed a linear relationship between the fluorescence intensity and ammonia gas concentration in the range of 20 ppm to 100 ppm. The developed optical sensor can be used for ammonia gas detection in a promising manner.
