Abstract
We report the effects of both anions and cations in lead halide perovskite-graphene hybrids applied to gas sensing. Ultra-fast sensors that can work at room temperature are developed and studied to elucidate the role in the gas sensing mechanisms of different ions in perovskite nanocrystals.
