摘要: 以石墨烯为代表的二维材料因其独特的结构和优异性能而受到广泛关注。随着二维材料在无限小的方向不断发展，二维（材料）量子片逐渐引起人们极大的兴趣。二维量子片不仅保留了二维材料的本征特性，而且表现出量子限域和突出的边缘效应，为二维材料的潜在应用带来全新机遇。本文详细介绍了二维量子片的基本概念，制备现状与光学性能的研究进展，特别强调了二维量子片本征、普适和规模制备的实现及其重大意义。此外，重点关注了二维量子片的光致发光特性以及在非线性光学、固态发光器件等领域的应用。最后，分析了二维量子片的发展趋势以及面临的主要挑战。Abstract: Two-dimensional (2D) materials like graphene have attracted much attention due to their unique structures and exotic properties. With significantly reduced lateral sizes, 2D quantum sheets (2D QSs) are attracting an increasing level of interest. 2D QSs have opportunities for new applications because of their intrinsic characteristics of being 2D materials and having emerging quantum confinement and prominent edge effects. This review focuses on the conceptual interpretation of 2D QSs and the recent progress on their preparation and optical properties. Particular focus is given to the realization and significance of the universal and scalable production of intrinsic 2D QSs. In addition, the photoluminescence of 2D QSs and their applications in nonlinear optics and solid-state light-emitting devices are reviewed. At the end, the perspectives and challenges towards the future development of 2D QSs are discussed.
