摘要
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.
