介绍了元素掺杂和表面钝化两种碳点的荧光增强途径,以改善原始碳点存在的荧光量子产率低、发光纯度低以及蓝绿区集中的发射等缺陷。同时,对碳点在重金属离子传感应用及发展进行了展望。
Two fluorescence enhancement methods for carbon dots,elemental doping and surface passivation,were elaborated to improve the defects of pristine fluorescent dots,such as low fluorescence quantum yield,low luminescence purity,and emission concentrated in the blue-green region.By the way,the application and development of carbon dots in heavy metal ions sensing were prospected.
