摘要
量子点由于其量子效应而具有既不同于体相材料又有别于一般分子的优异光学性能,因此在生物医学领域,特别是在生物标记中具有良好的应用前景。Ⅱ-Ⅵ族量子点由于其荧光发射波长几乎覆盖了整个可见光区而引起人们的关注,其中在有机体系中合成油溶性Ⅱ-Ⅵ族量子点具有反应产物稳定,量子产率高,并且可以制备性能更加优异的核-壳结构的量子点(CdSe/ZnS,CdSe/CdS等)等优点,因此在过去的十几年中被广泛而深入地研究。本文重点综述了在有机体系中,单分散、高荧光性能Ⅱ-Ⅵ族量子点的制备方法——高温热解法及其合成机理的研究进展,并对今后的研究方向作了展望。
Quantum dots (QDs) have became one of the most attractive fields of current research because of their unique optical properties. Ⅱ- Ⅵ group QDs have attracted a great interest for their potential bio-applications because of their excellent fluorescent properties in the visible range. In this article, the development of the preparation and synthesis mechanisms of the oil-soluble Ⅱ- Ⅵ group QDs in the organic system is reviewed and the future focus of the QDs research is prospected.
