Printed flexible photodetectors based on 2D inorganic perovskites with atomic thickness show excellent photosensing with fast rise and decay response times. As-synthesized nanosheets can easily be dispersed in various solvents, leading to large-area, crack-free, low-roughness, flexible films after printing. This study demonstrates that all-inorganic perovskite CsPbX3 nanosheets as a new class of 2D semiconductors have huge potential for flexible optoelectronic applications.
基于原子厚度的二维无机钙钛矿的打印柔性光电探测器具有出色的光电感应性能，其上升和下降响应时间都很快。合成的纳米片很容易分散在各种溶剂中，从而在打印后形成大面积、无裂纹、低粗糙度的柔性薄膜。本研究表明，全无机钙钛矿 CsPbX3 纳米片作为一种新型二维半导体，在柔性光电应用方面具有巨大的潜力。
