An unprecedented CsPbBr3-based polar Dion-Jacobson type bilayered hybrid, (2meptH2)CsPb2Br7 (1, where 2mept = 2-methyl-1,5-diaminopentane), has been reported. Polarization could benefit the charge transport to induce low Ntrap. 1 exhibits a large on/off ratio (∼103), fast response time (∼200 μs) and high photodetectivity (∼109 Jones) for promising UV photodetection.
已报道一种前所未有的 CsPbBr3 基极性 Dion-Jacobson 型双层混合体 (2meptH2)CsPb2Br7（1，其中 2mept = 2-甲基-1,5-二氨基戊烷）。极化可以促进电荷输运，从而降低 Ntrap。1 表现出大的开/关比（∼103）、快速响应时间（∼200 μs）和高光探测率（∼109 Jones），有望用于紫外光探测。
