英文摘要： Due to their unique quantum confinement effects, interface and edge structures, aqueous solubility and photoluminescence stablity, graphene quantum dots have received great attention recently.This research will focus on controlled synthesis and structure-property characterizations of graphene quantum dots and nitrogen-doped graphene quantum dots and their applications in biomedical fluorescence imaging. The aims of the research are to develop a novel method for the synthesis of graphene quantum dots and nitrogen-doped graphene quantum dots with controlled morphology, dimension, and energy band gaps; study their photoluminescence mechanisms; improve their luminescence quantum efficieny; and investigate their potential applications in biomedical fluorescence imaging. Therefore, the conduct of this project will broaden potential applications of graphene quantum dots in biomedical imaging, fuel cells, and biosensors as well as provide theoretical and experimental supports for the development of novel fluorescence imaging materials and technology.
