摘要

Abstract

Low-dimensional materials exhibit unique quantum confinement effects and morphologies as a result of their nanoscale size in one or more dimensions

making them exhibit distinctive physical properties compared to bulk counterparts. Among all low-dimensional materials

due to their atomic level thickness

two-dimensional materials possess extremely large shape anisotropy and consequently are speculated to have large optically anisotropic absorption. In this work

we demonstrate an optoelectronic device based on the combination of two-dimensional material and carbon dot with wide bandgap. High-efficient luminescence of carbon dot and extremely large shape anisotropy (> 1500) of two-dimensional material with the wide bandgap of > 4 eV cooperatively endow the optoelectronic device with multi-functions of optically anisotropic blue-light emission

visible light modulation

wavelength-dependent ultraviolet-light detection as well as blue fluorescent film assemble. This research opens new avenues for constructing multi-function-integrated optoelectronic devices via the combination of nanomaterials with different dimensions.
