Two-dimensional organic-inorganic hybrid perovskites (2D OIHPs) have attracted extensive attention in the field of X-ray detection due to their excellent stability compared to traditional three-dimensional OIHPs and the strong optoelectronic response to X-ray along the quantum wells. In this review, the nucleation and growth process as well as intermolecular forces for controlling out-of-plane growth are summarized along with the oriented growth mechanism. The optoelectronic properties in 2D OIHP under irradiation of X-ray are also discussed. Finally, conclusions and outlook for orientation 2D OIHP quantum wells and their challenges in application of direct X-ray detection are given. This review will provide a basic understanding on the strategy of designing 2D OIHP thick films as promising X-ray photoconductors, which may inspire the development of next-generation X-ray detectors.
二维有机-无机杂化钙钛矿（2D OIHPs）由于与传统三维OIHPs相比具有出色的稳定性，以及沿量子阱对X射线具有强烈的光电响应，在X射线检测领域引起了广泛关注。在这篇综述中，总结了成核和生长过程以及控制面外生长的分子间力，并阐述了取向生长机制。还讨论了2D OIHP在X射线照射下的光电特性。最后，给出了取向2D OIHP量子阱的结论与展望及其在直接X射线检测应用中的挑战。这篇综述将为设计作为有前景的X射线光电导体的2D OIHP厚膜的策略提供基本理解，这可能会推动下一代X射线探测器的发展。
