摘要
以葡萄糖为碳源,2、4、6-三胺基嘧啶为氮源,制备掺杂前驱体后通过真空高温退火,生长得到氮掺杂型石墨烯薄膜,并对生长得到的氮掺杂型石墨烯薄膜进行了各类光电性能表征。通过拉曼表征证实该薄膜是多层石墨烯薄膜,有一定的缺陷,但结晶度较好。XPS表征也证实氮元素成功地掺杂进石墨烯晶格结构中,并以共价键结合。通过透射电镜表征,薄膜表面附着许多∅20~30 nm量子点,薄膜形态比较致密。UV-Vis吸收光谱测试证实,该掺杂的石墨烯薄膜吸收峰产生一定程度的蓝移,掺杂氮元素后薄膜对可见光整体吸收能力加强。
In this paper,using glucose as carbon source and 2,4,6-triamino-pyrimidine as nitrogen source,nitrogen-doped graphene films were grown by vacuum annealing at high temperature,and various photoelectric properties of the grown nitrogen-doped graphene films were characterized.Raman characterization confirmed that the film is a multilayer graphene film with certain defects but crystallinity is good.XPS characterization also confirmed that nitrogen was successfully doped into the graphene lattice structure and covalent bond.Through transmission electron microscopy,many quantum dots with diameters of 20~30 nm are attached to the surface of the film,and the film morphology is relatively dense.The UV-Vis absorption spectrum test confirmed that the absorption peak of the doped graphene film produced a certain degree of blue shift,and the overall absorption capacity of the film was enhanced after nitrogen doping.
