| 中文摘要: |
| 在半导体领域，通过合金化集成两种以上半导体的单纳米结构近年来相继问世，随着纳米材料的成分变化，可以灵活实现半导体的带隙调控，在光通信以及集成光电器件领域有着广泛的应用。然而，传统半导体纳米结构因不同成分之间存在晶格失配，其带隙调节的范围受到了很大限制。因此，钙钛矿作为对晶格失配具有高容忍度的半导体材料，在半导体带隙调控及器件研究领域显示出了巨大的潜力。本文综述了无机卤化物钙钛矿一维合金纳米材料的合成方法以及近年来的研究进展，总结了可调带隙钙钛矿一维合金纳米材料在光电子器件领域中的应用，包括波长可调谐纳米激光器、光电探测器、白光发光二极管、全光开关、太阳能电池等。实现单纳米结构带隙工程将对未来集成器件的发展产生深远的影响。 |

| In the field of semiconductors, single nanostructures that integrate more than two semiconductors by alloying have emerged in recent years. With the change of the composition of nanomaterials, flexible bandgap tuning can be achieved, and they are widely used in optical communications and integrated optoelectronic devices. However, the bandgap adjustment range of traditional semiconductor nanostructures is limited due to the lattice mismatch between different components. Therefore, perovskite, as a semiconductor material with high tolerance to lattice mismatch, shows great potential in the field of bandgap regulation. In this paper, the synthesis methods of inorganic halide perovskite one-dimensional alloy nanomaterials and some research progress in recent years are reviewed. Finally, the application of tunable bandgap perovskite one-dimensional alloy nanomaterials in the field of optoelectronic devices is summarized, including tunable wavelength nanolasers, photodetectors, white light-emitting diodes, all-optical switches, solar cells, etc. The realization of single nanostructure bandgap engineering will have a far-reaching impact on the development of integrated devices in the future. |
