【摘要】：二维钙钛矿作为一种新型光电材料,既具有二维材料的可溶液加工、柔性、可穿戴性以及廉价容易制备等特点,又具备钙钛矿材料结晶度高、载流子迁移率高、激子束缚能低、量子效率高、吸收光谱宽、光吸收系数高和能耗损失低等特性,已经成为材料研究领域的热点而受到广泛关注。本文深入分析了二维钙钛矿材料的组成特点及结构构建规则,探究了其光电特性、能带性质以及非线性光学性质等,对二维钙钛矿光电材料常见的两大类制备方法液相法和气相法进行了归纳,总结了二维钙钛矿材料在太阳能电池、光电探测器、发光二极管、场效应晶体管和激光等光电器件领域的应用现状,最后对该类材料目前存在的主要问题及未来发展前景进行了展望,以期为设计制备高性能二维钙钛矿光电材料提供参考。
[Abstract]:As a new type of optoelectronic material, two-dimensional perovskite has the advantages of high crystallinity, high carrier mobility and low exciton binding energy. Due to its high quantum efficiency, wide absorption spectrum, high optical absorption coefficient and low energy loss, it has become a hot topic in the field of materials research. In this paper, the composition characteristics and construction rules of two-dimensional perovskite materials are analyzed in depth, and the photoelectric, band and nonlinear optical properties of the perovskite materials are discussed. In this paper, two kinds of preparation methods of two-dimensional perovskite optoelectronic materials, liquid phase method and gas phase method, are summarized, and the applications of two-dimensional perovskite materials in solar cells, photodetectors, light-emitting diodes are summarized. The applications of field effect transistors and lasers in the field of optoelectronic devices are reviewed. At last, the main problems and future prospects of these materials are discussed in order to provide a reference for the design and fabrication of high performance two-dimensional perovskite optoelectronic materials.
