The photoluminescence mechanism in carbon dots (graphene quantum dots, carbon nanodots, and polymer dots): current state and future perspective
TL;DR: The actual mechanism of photoluminescence (PL) of fluorescent carbon dots (CDs) is still an open debate among researchers as mentioned in this paper, and three types of fluorescent CDs were involved: graphene quantum dots (GQDs), carbon nanodots (CNDs), and polymer dots (PDs).
