应用 石墨烯量子点（GQD）是横向尺寸小于100 nm的几层石墨烯片，具有很强的量子限域和边缘效应。因此，它们具有独特的物理性质，如强光致发光，可通过控制其尺寸、形状、缺陷和功能而针对特定应用进行定制。 与经典的QD（如金属或硅量子点）相比，GQD具有生物相容性、光稳定性并且继承了石墨烯出色的热力性质、电性质和机械性能。这些功能大大促进了各种最先进的光学增白剂。 用于安全应用的爆炸物示踪剂。 生物成像标记物。 荧光聚合物。 抗菌、抗生物污染、消毒系统。 重金属、湿度和压力传感器。 电池。 闪存设备。 光伏设备。 发光二极管。 Application Graphene quantum dots (GQDs), sheets of few-layered graphene and lateral dimensions smaller than 100 nm, possess strong quantum confinement and edge effects. Thus, they possess unique physical properties such as strong photoluminescence, which can be tailored for specific applications by controlling their size, shape, defects, and functionality. In contrast to classic QDs, such as metal or silicon quantum dots, GQDs are biocompatible, photo-stable, and inherit superior thermal, electrical, and mechanical properties from the graphene. These features can greatly contribute to various state-of-the-art applications: Optical brighteners. Taggants for security application. Bioimaging markers. Fluorescent polymers. Antibacterial, antibiofouling, disinfection systems. Heavy metals, humidity and pressure sensors. Batteries. Flash memory devices. Photovoltaic devices. Light-emitting diodes.
