Abstract

Abstract : Photodetecting Paper In article number 2200563, Xiaohong Chen, Duanjun Cai, and co‐workers develop a solar‐blind photodetecting paper based on ZnO nanoarray and 2D h‐BN interlayer with ultrahigh responsivity up to 700 A W −1 @ 265–276 nm and switchable detection bands between UVA (>315 nm) and UVC (<280 nm), through up‐conversion absorption and negative differential resistance effect.
