Abstract

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 cation intercalation (ACI)-type MHPs, with excellent optoelectronic properties and a 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; R-PPA = R-1-phenylpropylamine; PA = propylamine). 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, 1R shows 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, meeting the state-of-the-art level by leveraging its intrinsic photovoltaic effect. These findings highlight the huge potential of chiral-polar ACI-type MHPs in self-driven X-ray detection applications.

手性极性交替阳离子插层型钙钛矿实现了具有超低检测极限的灵敏自驱动x射线检测
金属卤化物钙钛矿(MHPs)在直接x射线检测方面显示出巨大的潜力,但在没有外部偏置的情况下实现高灵敏度仍然具有挑战性。手性极性交替阳离子插层(ACI)型MHPs具有优异的光电性能和强大的手性诱导体光伏效应(BPVE),为自驱动x射线检测提供了一个有前途的平台。本文利用手性极性2D aci型钙钛矿单晶(R-PPA)PAPbBr4 (1R;R-PPA = r -1-苯丙胺;PA =丙胺)。手性R-PPA阳离子在手性极性空间基团P21中诱导1R结晶,其自发电极化进一步诱导强BPVE。因此,1R具有显著的0.75 V的辐射光伏,这使得其具有优异的自驱动x射线检测能力,其灵敏度高达417.2 μC Gy-1 cm-2,检测限低至24.1 μ y s-1,利用其固有的光伏效应达到了最先进的水平。这些发现突出了手性极性aci型MHPs在自驱动x射线检测应用中的巨大潜力。
