| 摘要 | Metal halide perovskites (MHPs) have shown great potential for direct X-ray detection, but achieving high sensitivity without external bias remains challenging. Chiral-polar alternating cations intercalation-type (ACI) MHPs, with excellent optoelectronic properties and robust chirality-induced bulk photovoltaic effect (BPVE), offer a promising platform for self-driven X-ray detection. Herein, impressive self-driven X-ray detection performance was achieved by utilizing chiral-polar 2D ACI-type perovskite single crystals of (R-PPA)PAPbBr4 (1R). The chiral R-PPA cations induce the crystallization of 1R in the chiral-polar space group P21, wherein its spontaneous electric polarization further induces a strong BPVE. Consequently, 1Rshows remarkable radiation photovoltaics of 0.75 V, which endows its excellent self-driven X-ray detection with a high sensitivity of 417.2 μC Gy-1 cm-2 and a low detection limit of 24.1 nGy s-1 , which meets the state-of-art level by leveraging their intrinsic photovoltaic effect. These findings highlight the huge potential of chiral-polar ACI-type MHPs in self-driven X-ray detection applications. |
