| Summary: | <p dir="ltr">We report the development of a high sensitivity H<sub>2</sub>S 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 (FAPbBr<sub>3</sub>), which exhibits a high sensitivity to H<sub>2</sub>S gas in the form of changes to the electrical conductivity. The response of the sensor to H<sub>2</sub>S 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.</p><h2>Other Information</h2><p dir="ltr">Published in: Results in Physics<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.rinp.2022.105333" target="_blank">https://dx.doi.org/10.1016/j.rinp.2022.105333</a></p> |
