| Abstract | We report the development of a high sensitivity H2S gas sensor based on perovskite nanoparticles, which can be synthesized using relatively simple solution-growth methods. The gas sensor was fabricated from the metal halide perovskite formamidinium lead bromide (FAPbBr3), which exhibits a high sensitivity to H2S gas in the form of changes to the electrical conductivity. The response of the sensor to H2S gas showed a high sensitivity to gas concentrations in the range 0.5 – 100 ppm, with a fast response time of less than one minute under ambient room conditions. |
