Abstract
Multicolor photoluminescent graphene quantum dots (GQDs) with a uniform size of ∼60 nm diameter and 2-3 nm thickness were prepared by using unsubstituted hexa-peri-hexabenzocoronene as the carbon source. This result offers a new strategy to fabricate monodispersed GQDs with well-defined morphology.
摘要
采用未取代的六苯并蔻作为碳源，制备了具有均一尺寸（约 60nm 直径和 2-3nm 厚度）的多色光致发光石墨烯量子点（GQDs）。该结果为制备具有良好形态定义的单分散 GQDs 提供了一种新策略。
