摘要: 甲脒碘化铅(FAPbI3)钙钛矿因其在光电领域的潜在应用而备受关注，然而其在室温下极易发生相变转变为δ相，其结构、发光性质等与α相差异明显，严重制约了它的实际应用。因此，深入研究FAPbI3的相变机制及其光学性质的温度依赖性对于提高材料的稳定性和实际应用具有重要意义。本文综述了近年来关于FAPbI3相变的研究进展，总结了不同相的晶格振动特性、光学性质以及晶体结构特点，并对未来研究方向进行了展望，旨在为深入理解FAPbI3钙钛矿相变机制和实现其在光电领域的实际应用提供参考。
Abstract: Formamidine lead iodide (FAPbI3) perovskite has attracted much attention due to its potential applications in the field of optoelectronics. However, it is very easy to phase transformation to the δ phase at room temperature, and its structure and luminescence properties are obviously different from those of α phase, which severely restricts its practical application. Therefore, in-depth research on the phase transition mechanism of FAPbI3 and the temperature dependence of its optical properties is of great significance for improving the material’s stability and practical application. This paper reviews the research progress on the phase transition of FAPbI3 in recent years, summarizes the lattice vibration characteristics, optical properties, and crystal structure features of different phases, and looks forward to future research directions, aiming to provide a reference for a deeper understanding of the phase transition mechanism of FAPbI3 perovskite and its practical application in the field of optoelectronics.
