Abstract
The present invention provides a process for preparing carbon quantum dots having uniform size by using emulsion, and a process for doping the inside of the carbon structure with other element or replacing the surface with a surface stabilizer having a specific chemical functional group different from existing stabilizers in order to control the properties of the carbon quantum dots. The process for preparing the carbon quantum dots according to the present invention makes a mass production possible and the process thereof is simple. Furthermore, the process is easy to control the size of the quantum dots and the reaction yield rate of the method is excellent. In addition, according to the present invention, it is possible to synthesize carbon quantum dots having uniform size and superior quantum yield rate and it makes it possible to embody the color as equivalent to existing molecular chromophores or heavy metal quantum dots by changing the structure of the chromophore.
