摘要：二维材料与固态材料相比，具有许多不同的性质。这些都是由于二维材料的结构：

电子被约束在一个平面内，运动速度特别大。二维材料在很多行业有着广泛的应用前景。所以研究人员对二维材料进行了大量的研究。伴随着二维材料的研究热潮，这些二维材料的量子点也开始逐步进入科学家视野，对这些二维材料的量子点进行了大量研究。由于二维材料与其块体材料的性质有很大不同，科学家也期待这些材料的量子点能够有更好的性能。

锑烯量子点是近年来人们普遍关注的新型量子点材料。由于单层锑烯是具有高度稳定性、宽带隙的新型二维半导体，因此科学家也期待锑烯量子点能表现出优异的性能。在此课题中，主要介绍了如何利用液相剥离法制备锑烯量子点，并且对制备的锑烯量子点进行了表征。

Title   Antimonene  Quantum Dots by Liquid-Phase Exfoliation       

Abstract：Two-dimensional materials have many different properties compared to solid materials. These are due to the structure of two-dimensional materials: electrons are constrained in a plane, the movement speed is particularly large. Two-dimensional materials in many industries have a wide range of applications. So the researchers on the two-dimensional materials for a lot of research. With the research of two-dimensional materials, the quantum dots of these two-dimensional materials have begun to gradually enter the field of scientists, and the quantum dots of these two-dimensional materials have been studied extensively. Because the two-dimensional materials are very different from the properties of their bulk materials, scientists also expect quantum dots of these materials to have better performance. 

The antimony ene quantum dots are new quantum dots materials that have been widely concerned in recent years. As a single layer of antimony is a highly stable, wide band gap of the new two-dimensional single-element semiconductor. So scientists also expect antimony ene dots to exhibit excellent performance. In this paper, we mainly introduce how to prepare antimonyene quantum dots by liquid stripping method, and characterize the prepared antimonyene quantum dots.

1.1 引言

2004年，曼彻斯特大学的安德里·海姆和KonstantinNovoselov从石墨上分离出单原子层的二维晶体材料[1]：石墨烯。引起了极大的轰动。因为在当时，Mermin-Wagner定理认二维材料不可能存在，即使条件放松，也认为只有在相当低的温度下可能找到准二维晶格。但石墨烯是在室温下制备出来的，推翻了原先的假设。从此就掀起了探索二维材料的热潮。2010年诺贝尔物理学奖也因此颁发给两位科学家。 液相剥离法制备锑烯量子点:http://www.youerw.com/huaxue/lunwen_205041.html
