Recently, organic semiconductor-incorporated perovskites (OSiPs) have emerged as a new subclass of next-generation organic-inorganic hybrid materials. OSiPs combine the advantages of organic semiconductors, such as large design windows and tunable optoelectronic functionalities, with the excellent charge-transport properties of the inorganic metal-halide counterparts. OSiPs provide a new materials platform for the exploitation of charge and lattice dynamics at the organic-inorganic interfaces for various applications. This Perspective reviews recent achievements in OSiPs highlighting the benefits from organic semiconductor incorporation and elucidates the fundamental light-emitting mechanism, energy transfer, as well as band alignment structures at the organic-inorganic interface. Insights on the emission tunability lead toward a discussion of the potential of OSiPs in light-emitting applications, such as perovskite light-emitting diodes or lasing systems.
最近，含有机半导体的钙钛矿（OSiPs）已成为下一代有机-无机杂化材料的一个新子类。OSiPs结合了有机半导体的优点，如大的设计窗口和可调谐的光电功能，以及无机金属卤化物对应物优异的电荷传输特性。OSiPs为在有机-无机界面开发电荷和晶格动力学以用于各种应用提供了一个新的材料平台。本视角综述了OSiPs的近期成果，突出了引入有机半导体带来的益处，并阐明了基本的发光机制、能量转移以及有机-无机界面处的能带排列结构。对发射可调谐性的见解引发了对OSiPs在发光应用（如钙钛矿发光二极管或激光系统）中的潜力的讨论。
