Yunqian Dai and co‐workers report on page 597 how N dopants are tailored in the form of both substitutional and pyrrolic N in graphene quantum dots (N‐GQDs), showing controllable chemical properties. The substitutional N leads to significantly modified photoluminescence properties of the versatile N‐GQDs, which also exhibit highly efficient photocurrent conversion abilities when supported by anatase nanofibers.
