We report that the integration of filter membrane and Ca2Nb3O10 nanosheets (FM@CNO) UV photodetector (UV PD) shows high performance and excellent flexibility. The Ca2Nb3O10 nanosheets were prepared by a facile solid-state reaction and liquid exfoliation process. The Ca2Nb3O10 nanosheets can be integrated into the pores of a filter membrane via a simple vacuum filtration method. The FM@CNO UV PD shows high performance under 300 nm light illumination at 5 V bias, including high responsivity (0.08 AW−1), high detectivity (1.1 × 1012 Jones), high UV/visible rejection ratio (3.86 × 103) and fast speed (0.12/1.24 ms). Furthermore, the FM@CNO device exhibits excellent flexibility after many bending cycles. In addition, the FM@CNO array device was used as a pixel array detector for UV imaging. This work provides a novel approach to achieve high performance flexible PDs based on filter membrane and two dimensional materials.
