摘要

•Cs4PbBr6/CsPbBr3 perovskite were synthesized by controlling the synthesis temperature.•Cs4PbBr6/CsPbBr3 perovskite exhibited good stability compared to CsPbBr3.•Sensitive detection of DNPH was realized based on the Cs4PbBr6/CsPbBr3 perovskite.•The Cs4PbBr6/CsPbBr3-based fluorescent sensor was used to detect DNPH in soil samples.
