摘　　要：近年来,纳米晶体(量子点)以及量子点光纤、量子点光纤放大器成为一个研究热点。介绍了CdSe/ZnS和PbSe量子点的光谱特性以及量子点的吸收-辐射截面,表明量子点具有强的吸收和发射。总结了低浓度和较高浓度CdSe/ZnS量子点掺杂光纤、熔融法及溶胶凝胶法制备PbSe量子点光纤材料的最新研究进展,分析了两种方法制备量子点光纤材料的优缺点,概述了PbSe量子点光纤放大器的研究近况,展望了量子点光纤的应用前景。Quantum dots（QDs）, quantum dot doped fibers（QDFs） and quantum dot doped fiber amplifiers （QDFAs） are ones of the research focuses in recent years. In this study, the spectral characteristics and absorption-emission cross section of the CdSe/ZnS and PbSe QDs were described. The results showed that QDs had enhanced absorption and emission. The research advances were summarized for the CdSe/ ZnS QD doped fibers with different QD concentrations, and for the PbSe QDF materials fabricated by fusion and sol-gel method. The advantages and disadvantages of the methods in preparing QDF materials were analyzed. In addition, the researches on the PbSe QDFA were reviewed. A suggestion was given for potential applications of the QDFs in the future.
