While halide perovskites (HPs) have achieved enormous success in the field of optoelectronic applications, much attention has been recently drawn to the unique polarization sensitivity of HPs, either intrinsic or extrinsic, which makes HPs a potential candidate for innovative applications in directly polarized luminescence and detection. Herein, the research status in the field of polarization-sensitive HPs, including linear polarization and circular polarization, is comprehensively summarized. To evaluate the effectiveness of HPs in generating and detecting linearly or circularly polarized light, the principles and characterization methods of polarized luminescence and detection are introduced. Sequentially, the state-of-the-art development of the strategies that induce the linear or circular polarization characteristics of HPs is systematically reviewed, based on which the application of polarization-sensitive HPs in the field of polarization luminescence and detection are summarized. Moreover, the current challenges and opportunities are discussed, and prospects of the future development in this promising field are outlined.
尽管卤化物钙钛矿（HPs）在光电子应用领域取得了巨大成功，但最近人们对HPs独特的极化敏感性给予了极大关注，这种极化敏感性无论是内在的还是外在的，都使HPs成为直接极化发光和检测等创新应用的潜在候选材料。在此，全面总结了极化敏感型HPs领域的研究现状，包括线性极化和圆极化。为了评估HPs在产生和检测线性或圆偏振光方面的有效性，介绍了偏振发光和检测的原理及表征方法。随后，系统地综述了诱导HPs线性或圆极化特性的策略的最新进展，并在此基础上总结了极化敏感型HPs在偏振发光和检测领域的应用。此外，还讨论了当前面临的挑战和机遇，并概述了这一充满前景的领域未来发展的前景。
