The use of pre-oxidation of graphite sheets of water and heat cutting method can produce nanoscale graphene quantum dots water-soluble fine, in the process, also reports obtained blue photoluminescence phenomenon. This might lead to the graphene-based optoelectronics materials application expanded to more areas and biological labeling.
Due to the graphene-based materials for the superior of the electronic, thermal, mechanical properties and chemical stability, so they are likely the future of 原材料 making nano Qi Jian. However, through traditional methods to create out of graphene-based material is usually only microns size of graphene layers. In order to apply them in nano-devices, we need to design a more effective way to cut into the specified Ceng Jiang graphene’s Xing Zhuang, and size to the nanoscale. Pan et al reported a hydrothermal method, which can be pre-cut sheets of graphite oxide graphene quantum dots water-soluble fine. Apart from the acidic and alkaline media to establish the structural model of quantum dots, it also found that the blue photoluminescence phenomenon. This may mean that in graphene-based materials can also be applied to other areas, such as opto-electronics and bio-labeling.
