量子点因具有优异的光电特性，近年来备受关注。但量子点的规模化应用因受到其加工工艺及稳定性等因素限制而尚待开发。量子点-聚合物纳米复合材料的出现有效弥补了这一问题，将量子点分散到有机聚合物中形成纳米复合材料，集合量子点与聚合物的各自优势于一体，是解决量子点当前应用问题的一种有效方法，具有显著的发展潜力。文中介绍了量子点的主要制备技术，并在此基础上对量子点-聚合物复合材料的制备方法及其在激光器、发光二极管、光电探测器、量子点电视等光电子器件中的应用进展进行了概述，最后对其在光电器件领域的应用进行了展望。

Quantum dots have attracted much attention in recent years because of their excellent photoelectric properties. However, the large-scale application of quantum dots has yet to be developed due to its processing technology and stability. The emergence of quantum dot-polymer nanocomposites effectively makes up for this problem. It is an effective method to solve the current application problems of quantum dots by disperses quantum dots into organic polymers to form nanocomposites and integrates the respective advantages of quantum dots and polymers. It has significant development potential. The main preparation technology of quantum dots was introduced, on this basis, the preparation methods of QD-polymer composites and their applications in lasers, light emitting diodes, photodetectors, QD-TVs and other optoelectronic devices were summarized, and finally its application in the field of optoelectronic device was prospected.
