摘要
石墨烯量子点是一类重要的石墨烯衍生物,在量子尺寸效应的作用下,石墨烯量子点显示出与传统石墨烯截然不同的半导体特性。目前,石墨烯量子点以其优异的光致发光特性,高稳定性,低生物毒性,可调制的界面结构,在荧光防伪材料、生物成像、肿瘤诊疗、光/电催化等领域展现出突出的优势。从石墨烯量子点光致发光特性出发,对石墨烯量子点的带隙这一关系到该材料在各应用领域的重要基本物性进行总结,旨在明确当前在石墨烯量子点光致发光机制研究、光致发光性能调制两大领域的研究进展与挑战。
Graphene quantum dot is one of the most important derivants of graphene. With the quantum size effect, graphene quantum dots show a distinct semiconductive nature, compared with intrinsic graphene. Graphene quantum dots have a high application value in fluorescent anti-counterfeiting materials, biological imaging, tumor diagnosis and treatment, and photo/electrocatalysis due to their superior photoluminescence properties, high stability, low biotoxicity, modulated interface structure. This review represented the photoluminescence properties of graphene quantum dots. The bandgap structure of graphene quantum dots, which is related to the important basic physical properties of the material in various applications was summarized. This review can provide a reference for the future studies on the photoluminescence performance modulation and mechanism of graphene quantum dots.
