The present invention relates to a contrast agent comprising a carbon nitride material emitting high-dispersion and long-wavelength fluorescence light and a method for manufacturing the same. can be manufactured. Accordingly, in vitro fluorescence imaging as well as in vivo fluorescence imaging, which was not possible with the prior art, can be implemented, and thus, there is an effect that can be provided to pharmaceutical products such as a contrast agent for disease diagnosis and a contrast agent for tracking cells. |
