Abstract

We fabricated an alcohol detector based on (PEA)(CHNH)SbBr ((PEA)MASbBr) lead-free perovskite-like films. The XRD pattern revealed that the (PEA)MASbBr 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)MASbBr 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.

摘要

我们基于（PEA）（CHNH）SbBr（（PEA）MASbBr）无铅类钙钛矿薄膜制备了一种酒精探测器。X射线衍射图谱表明，（PEA）MASbBr无铅类钙钛矿薄膜呈现准二维结构。对于5%和15%的酒精溶液，最佳电流响应率分别为74和84。当薄膜中PEABr的量减少时，样品在高酒精浓度溶液的环境酒精中的电导率增加。由于准二维（PEA）MASbBr薄膜的催化作用，酒精被溶解成水和二氧化碳。该酒精探测器的上升和下降时间分别为1.85秒和0.7秒，表明该探测器是适用的。
