Abstract

Chemiresistive sensors offer a promising option for establishing extensive sensing networks, providing a cost-effective and energy-efficient solution. This study introduces novel hybrids consisting of lead halide perovskite nanocrystals decorating graphene, operable under ambient temperature conditions. Evaluating the impact of two cations (methylammonium and cesium) and two anions (chlorine and bromine), MAPbBr3 emerges as the most promising composition for NH3 detection at room tempera-ture.
