摘要
量子点(Quantum Dots,QDs)是一种零维纳米材料,其尺寸小于或接近激子玻尔半径.随着纳米技术的发展,金属硫化物量子点因其独特的光学、电学和磁学性质而受到广泛关注,可将其分为过渡金属硫化物量子点(TMDQDs)、Ⅱ-Ⅵ族量子点及Ⅳ-Ⅵ族量子点等.超声法制备量子点具有高效、环保、易于控制和可扩展性等优点,逐渐成为制备金属硫化物量子点的重要技术之一.金属硫化物量子点有着别于传统体相材料的优异光电特性,在近些年里,其优越而又独特的性能使得在更多的领域中得到了深入的研究和应用,如光电器件、生物成像、光催化等.本文综述了超声法制备不同金属硫化物量子点的研究进展,并对其性质和应用进行了归纳和总结.最后,对超声法制备金属硫化物量子点进行了展望.
Abstract
Quantum Dots(QDs)are zero-dimensional nanomaterials with dimensions less than or close to the exciton Bohr radius.With the development of nanotechnology,metal sulfide QDs has attracted wide attention due to their u-nique optical,electrical and magnetic properties,which can be classified into transition metal-disulfide QDs(TMD QDs),Ⅱ-Ⅵ QDs and Ⅳ-Ⅵ QDs.The ultrasonic method for the preparation of QDs has the advantages of high effi-ciency,environmental protection,easy control and scalability,and has gradually become one of the important tech-niques for the preparation of metal sulfide QDs.Metal sulfide QDs have excellent optoelectronic properties that are dif-ferent from those of traditional bulk materials,and their superior and unique properties have led to in-depth research and applications in more fields in recent years,such as optoelectronic devices,bio-imaging,and photocatalysis.In this paper,an overview of the preparation of different metal sulfide QDs by ultrasonication is reviewed,and their properties and applications are summarized and concluded.Finally,an outlook on the preparation of metal sulfide quantum dots by ultrasonication is given.
