Abstract
AbstractA new ultraviolet photodetector (UV PD) is successfully fabricated based on 2D NbWO6 (NWO) nanosheets for the first time, which is synthesized by a facile solid‐state reaction, ion exchange and liquid exfoliation process. The NWO nanosheet‐based PDs exhibit excellent UV detecting performance at 1 V at 290 nm, high responsivity (378 A W−1), high external quantum efficiency (EQE, 1.6 × 104%), high spectral selectivity (R290/R400 = 8.84 × 103) and fast speed (1.05/88 ms). Furthermore, the NbWO6 nanosheets film based PD shows great potential for the application in UV image sensing. This work provides a feasible strategy for the development of new UV PDs based on other potential layered niobates.
