Summary: Low-dimensional perovskites (LDPs) hold great potential for advanced optoelectronic devices and addressing stability issues in perovskite commercial applications. A self-established machine learning model is developed to predict the dimensionality of LDPs, achieving an accuracy rate of 92.3% for the test dataset. Polarity and electrostatic potential on the van der Waals surface of an organic spacer are identified as key factors determining the structure dimensionality. This work provides a typical paradigm for applying a multiple-classification strategy of machine learning in the study of LDPs.

Summary: Organic-inorganic hybrid metal halide perovskite has a high photoluminescence quantum yield (PLQY) in optoelectronics and photonics. However, the nonmetallic property of antimony (Sb) leads to low PLQY in antimony-based single crystals. Two perovskite-like single crystals, (8-HQ)(2)SbCl3 and (8-HQH)SbCl4, are grown to study their luminescence characteristics. The inductive effect of organic coordination and exciton effect in the metal octahedral skeleton play a crucial role in determining the luminescent properties.

Summary: This article introduces an atomic scale detection technique for studying the phase transition and optical properties of CsPbI3-xBrx perovskites. Through temperature-composition phase diagram and density functional theory calculations, it is proved that the phase transition is closely related to noncovalent interactions between bromine/iodine atoms. The study finds that the diversification of carrier mobility and diffusion length is significantly influenced by carrier-phonon coupling and efficient transport of excitons. This research contributes to a better understanding of perovskite phase transition and provides an innovative foundation for related applications like solar cells and optoelectronic devices.
