三维（3D）有机-无机金属卤化物钙钛矿材料由于钙钛矿材料的独特光电性质和光电子学的成本有效的制造可能性而具有接近高效光电子学的巨大潜在应用。然而，3D钙钛矿材料的科学和技术挑战是其长期稳定性较差，这阻碍了其实际应用。由有机层和无机层交替组成的低维钙钛矿材料是实现稳定的钙钛矿光致发光和光电子学的最可靠途径之一。在这篇简短的综述中，我们首先讨论了低维卤化物钙钛矿的晶体结构和非平凡的光电性质。综述了低维卤化物钙钛矿的合成方法。在此基础上，重点介绍了低维卤代钙钛矿在光致发光、发光二极管和激光器等方面的最新进展。最后，我们概述了低维卤化物钙钛矿的挑战及其应用。
Three-dimensional (3D) organic – inorganic metal halide perovskite materials possess great potential applications for approaching efficient optoelectronics due to the unique optoelectronic properties of perovskite materials and cost-effective manufacturing possibilities of optoelectronics. However, the scientific and technical challenges of 3D perovskite materials were their inferior long-term stability, which hampered their practical applications. The low-dimensional perovskite materials composed of alternating organic and inorganic layers are one of the most credible paths toward stable perovskite photovoltaics and optoelectronics. In this short review, we first present a discussion of the crystal structure and nontrivial optoelectronic properties of the low-dimensional halide perovskites. The synthetic methods for the preparation of the low-dimensional halide perovskites are reviewed. After that, we focus on the recent development of perovskite photovoltaics, light-emitting diodes, and lasers by the low-dimensional halide perovskites. Finally, we out-line the challenges of the low-dimensional halide perovskites and their applications.
