Abstract

Herein we report on the growth of layered BiI₃ nanoplates materials and their sensing properties of NO₂ under violet light illumination. The BiI₃ nanoplates were grown on a glass substrate using a chemical vapor deposition (CVD) system, with an average thickness of 30 nm and the lateral dimension of 150–170 nm. Their photo-induced sensing response for 20 ppm NO₂ and the response/recovery time are approximately ~11.2% and 18/36 s, respectively. The limit of detection (LOD) of NO₂ for the BiI₃ sensor is 25 ppb. A possible light-induced gas-sensing mechanism was proposed and investigated for the BiI₃ nanoplate.
