【 摘 要 】

We fabricated an alcohol detector based on (PEA)2(CH3NH3)3Sb2Br9 ((PEA)2MA3Sb2Br9) lead-free perovskite-like films. The XRD pattern revealed that the (PEA)2MA3Sb2Br9 lead-free perovskite-like films exhibited a quasi-2D structure. The optimal current response ratios are 74 and 84 for 5 and 15% alcohol solutions, respectively. When the amount of PEABr decreases in the films, the conductivity of the sample in ambient alcohol with a high alcohol concentration solution increases. The alcohol was dissolved into water and carbon dioxide due to the catalyst effect of the quasi-2D (PEA)2MA3Sb2Br9 thin film. The rise and fall times for the alcohol detector were 1.85 and 0.7 s, respectively, indicating that the detector was suitable.
