Abstract
We report that the integration of filter membrane and Ca2Nb3O10 nanosheets(FM@CNO)UV photode-tector(UV PD)shows high performance and excellent flexibility.The Ca2Nb3O10 nanosheets were pre-pared 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.
