▎ 摘　　要

Photobleaching of graphene quantum dots in an aggregated state on a silicon substrate, in polymer matrices, and in red blood cell membranes was studied using single-photon spectroscopy. Typical times of and changes in the emission statistics of graphene quantum dots were established. It was also found that changing the microenvironment of nanoobjects did not lead to significant correlations of emitted photons. The reported results are important for implementation of graphene quantum dots in biomedical imaging.
