摘要: 半导体量子点材料具有独特的光学和电学特性,在LED、太阳能电池、荧光探针、催化等领域显示出巨大的应用潜力,尤其是Ⅳ-Ⅵ族半导体量子点材料,荧光光谱处于近红外波段且可以覆盖光纤通信窗口,将其制备成量子点掺杂的光纤在光纤通信领域具有较为广泛的应用。目前Ⅳ-Ⅵ族半导体量子点掺杂光纤的制备方法主要有改进的化学气相沉积法、溶胶-凝胶膜涂覆法、空心光纤灌装固化法、高温熔融直接拉丝法、管内熔融法、玻璃毛细管灌入法等六种。本文详细综述了以上六种实验制备方法及其优缺点,以及所制备量子点光纤的光学增益品质;基于六种不同理论模型和光纤类型,总结了量子点掺杂光纤发光性质及光学增益性质的理论计算;进一步讨论了实验和理论研究中存在的问题、解决方法,并对未来研究方向进行了展望。

Abstract: Semiconductor quantum dot (QD) materials have unique optical and electrical properties, and have shown great potential for applications in LED, solar cells, fluorescent probes, catalysis, and other fields. Especially for Ⅳ-Ⅵ group semiconductor QD materials, their fluorescence spectra are in the near-infrared band and cover the optical fiber communication window. Therefore, QD doped optical fibers has a wide range of applications in the field of optical fiber communication. Currently, the main preparation methods for Ⅳ-Ⅵ group semiconductor QD doped optical fibers include modified chemical vapor deposition, sol-gel film coating, hollow fiber filling and solidification, high-temperature melting direct drawing, in-tube melting, and glass capillary injection. This paper provides a detailed review of these six experimental preparation methods, their advantages and disadvantages, as well as the optical gain quality of the prepared quantum dot optical fibers. Based on six different theoretical models and fiber types, theoretical calculations of the emission properties and optical gain properties of QD doped optical fibers are carried out. Furthermore, the challenges and solutions in experimental and theoretical research, as well as prospects for future research directions are given.
