▎ 摘　　要

Over the past 10 years, graphene quantum dots (GQDs) have grown into a highly innovative optical material in various research fields, including electronics, photonics, biotechnologies, etc. With the increasing implementation of GQDs in these fields, GQDs with tunable optical properties will emerge that could be especially suitable for applications in the field of integrated photonics. Herein, a short summary of the recent state of our research on the development of nitrogen-functionalized GQDs with tunable optical properties and their integration into photodetectors is given.
