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...
Films with excellent flexibility and mechanical stability are important for flexible and wearable devices. However, most films reported are prepared on substrates, and the synthesis of freestanding flexible films remains a challenge. Herein, a freestanding Bi2S3 nanofibrous membrane (NFM) is successfully prepared via a one‐step hydrothermal method, which is self‐assembled from ultralong Bi2S3 nanowires...
