Abstract

MXene (Mn+1Xn) is an emerging class of layered two-dimensional (2D) materials, which are derived from their bulk-state MAX phase (Mn+1AXn, where M: early transition metal, A: group element 13 and 14, and X: carbon and/or nitrogen). MXenes have found wide-ranging applications in energy storage devices, sensors, catalysis, etc. owing to their high electronic conductivity and wide range of optical absorption. However, the absence of semiconducting MXenes has limited their applications related to light emission. Research has shown that quantum dots (QDs) derived from MXene (MQDs) not only retain the properties of the parent MXene but also demonstrate significant improvement on light emission and quantum yield (QY). The optical properties and photoluminescence (PL) emission mechanisms of these light-emitting MQDs have not been comprehensively investigated. Recently, work on light-emitting MQDs has shown good progress, and MQDs exhibiting multi-color PL emission along with high QY have been fabricated. The synthesis methods also play a vital role in determining the light emission properties of these MQDs. This review provides an overview of light-emitting MQDs and their synthesis methods, optical properties, and applications in various optical, sensory, and imaging devices. The future prospects of light-emitting MQDs are also discussed to provide an insight that helps to further advance the progress on MQDs.

发光MXene量子点

MXene (Mn+1Xn)是一类新兴的层状二维(2D)材料，源于其体态MAX相(Mn+1AXn，其中M:早期过渡金属，A:族元素13和14,X:碳和/或氮)。由于其高电子导电性和广泛的光学吸收，MXenes在能量存储设备，传感器，催化等方面得到了广泛的应用。然而，半导体MXenes的缺乏限制了它们在发光方面的应用。研究表明，MXene衍生的量子点(QDs)不仅保留了母体MXene的特性，而且在光发射和量子产率(QY)方面也有显著改善。这些发光mqd的光学性质和光致发光机制尚未得到全面的研究。近年来，发光mqd的研究取得了良好的进展，已经制备出具有多色发光和高量子密度的mqd。合成方法对这些mqd的发光性能也起着至关重要的作用。本文综述了发光mqd及其合成方法、光学性质及其在各种光学、传感和成像器件中的应用。本文还讨论了发光mqd的未来前景，以提供有助于进一步推进mqd进展的见解。
