Large‐Area Freestanding Bi2S3 Nanofibrous Membranes for Fast Photoresponse Flexible IR Imaging Photodetector (Adv. Funct. Mater. 24/2023)

Abstract

Flexible IR Imaging Photodetectors In article number 2300159, Jinzhong Wang, Shiyong Gao, and co-workers, successfully prepared, a large-area freestanding Bi2S3 nanofibrous membrane (NFM) with high flexibility, which is self-assembled from ultralong Bi2S3 nanowires. The flexible photodetector based on the as-prepared Bi2S3 NFM exhibits high responsivity, fast response, excellent stability and splendent imaging capability under both flat and bent state. The as-prepared Bi2S3 NFM has great potential in flexible and wearable optoelectronic devices.
