摘　　要：以绿色环保的柠檬酸为碳源,二乙基三胺和聚乙烯亚胺为反应剂,采用水热法将生成的石墨烯量子点与滤纸基底复合,制得量子点荧光纸。荧光金相显微镜观察到制备的荧光纸在激发光的照射下发射均一的蓝色荧光,即荧光纸中的石墨烯量子点尺寸均一,在滤纸纤维表面上分布均匀。高灵敏度荧光光谱仪的检测显示,当水热反应的条件为180℃,反应时间为10 h,反应物浓度为3%时,制备的石墨烯量子点荧光纸在350 nm激发光作用下能够最强烈的荧光现象。Using green citric acid as carbon source, Diethyltriamine and polyethyleneimine as reactants, graphene quantum dots(QDs) were compounded with filter paper substrate by hydrothermal method to prepare QDs fluorescent paper. The graphene quantum dots fluorescent paper emitted uniform blue fluorescence under excitation light irradiation on fluorescent metallographic microscope, that is, the graphene quantum dots in the composites were uniform in size and distributed uniformly on the surface of the filter paper fiber. The detection by the high-sensitivity fluorescence spectrometer showed that when the hydrothermal reaction condition was 180 ℃, the reaction time was 10 h, and the reactant concentration was 3%, the prepared graphene quantum dots fluorescent paper could have the strongest fluorescence phenomenon under the excitation light action of 350 nm.
