Introduction to the difference between graphene quantum dots and carbon quantum dots
Graphene quantum dots and carbon quantum dots, although both belong to carbon nanomaterials, there are significant differences in many aspects.
1.From a structural point of view, graphene quantum dots are nanoscale materials cut from single or multilayer graphene, and their structures show the characteristics of two-dimensional planes. Carbon quantum dots, on the other hand, are zero-dimensional carbon nanomaterials, which are usually made of organic matter through pyrolysis or carbonization, and their structure is spherical or nearly spherical. This difference in structure makes the two different in physical and chemical properties.
2.In terms of properties, graphene quantum dots have excellent electron transport properties due to their unique two-dimensional structure, and also have excellent performance in optics and thermals. Carbon quantum dots, on the other hand, exhibit good biocompatibility and fluorescence properties due to their zero-dimensional structure, high specific surface area and abundant surface functional groups.
3.In terms of application, graphene quantum dots are widely used in electronic devices, solar cells, optoelectronic devices and other fields due to their excellent electron transport properties. Carbon quantum dots are widely used in bioimaging, drug delivery, biosensors and other fields due to their good biocompatibility and fluorescence properties.
4.In summary, there are significant differences between graphene quantum dots and carbon quantum dots in terms of structure, properties, and applications. These differences make the two have unique advantages and potential in their respective application fields, and provide new directions and possibilities for the development and application of carbon nanomaterials.
