Progress on two-dimensional quantum sheets and their optics

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 pre-paration 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.
