In this study, we investigate how modulating organic spacers in perovskites influences their X-ray detection performance and reveal the mechanism of low-dose with high sensitivity using femtosecond-transient absorption spectroscopy (fs-TAS). Particularly, employ N,N,N',N'-tetramethyl-1,4-phenylenediammonium (TMPDA) N,N-dimethylphenylene-p-diammonium (DPDA) as to synthesize 2D perovskite single crystals (SCs). We find that DPDA-based SCs exhibit reduced interplanar spacing between inorganic layers, leading increased lattice packing. Density functional theory (DFT) results indicate effective mass lower distortion (DPDA)PbBr4 suppressing formation self-trapped exciton (STEs) electron-phonon coupling enhancing carrier delocalization these SCs. Further, measurements demonstrates higher than (TMPDA)PbBr4, attributed its enhanced delocalization, mobility-lifetime product. The limit (LoD) for is determined be 13 nGy/s, significantly both commercial detectors state-of-the-art perovskite-based detectors. Furthermore, fs-TAS study reveals prolonged hot STE cooling decay lifetimes, which directly correlate sensitivity. This highlights impact on performance, providing a framework designing ultra-low LoD essential health security applications.

Abstract Organic–inorganic metal halides (OIMHs) exhibit a rich structural diversity and excellent semiconductor properties, making them attractive candidates in the field of nonlinear optics (NLO). Second harmonic generation, as an important NLO property, imposes strict symmetry constraints, requiring noncentrosymmetric structures. Currently, key task is to design structures for OIMHs explore relationship between structure performance. This will help further optimize application materials. The can be facilitated by use chiral organic cations or distorted inorganic polyhedra, both which induce features that favor noncentrosymmetry. properties are summarized performance analyzed, research directions these materials elaborated.
