摘要

Square-shaped microsheets of 2D lead-free perovskite (PEA)₂SnI_4-xBr_x (x = 0, 1, 2) were prepared via a ternary-solvent method. The photodetector based on the (PEA)₂SnI₄ microsheets gave a photoresponsivity of 3.29 × 10³ A W^-1, a specific detectivity of 2.06 × 10¹¹ Jones and a photoconductive gain of 8.68 × 10³. This is the first time that 2D lead-free perovskite microsheets are used to make high-performance photodetectors.
