水溶性石墨烯量子点（GQD，ca. 10 nm直径），表现出明亮的蓝色光致发光（PL）的制备通过水热（化学）切割氧化石墨烯片（见图）。讨论了切割和发光的机理。GQD的PL的发现可能会扩展石墨烯基材料在光电子学和生物标记方面的应用范围。
Water-soluble graphene quantum dots (GQDs, ca. 10 nm in diameter) that exhibit bright blue photoluminescence (PL) are prepared by hydrothermal (chemical) cutting of oxidized graphene sheets (see figure). The mechanisms of the cutting and luminescence are discussed. his discovery of PL of GQDs may extend T the range of application of graphene-based materials to optoelectronics and biological labeling.
