We demonstrate high-performance photodetectors based on Eu-doped 2D perovskite nanowire arrays. The pure crystallographic orientation enables efficient carrier transport and the doped Eu ions effectively suppress the trap density in the nanowire arrays. As a result, the optimized Eu-doped photodetectors show an excellent responsivity of 6.24 A W-1, an outstanding specific detectivity of 5.83 × 1013 Jones and stable photo-switching behavior with a current on/off ratio of 103.
