Reduced graphene oxide quantum dots (rGOQDs) were synthesized by annealing GOQDs in H-2 atmosphere. The photoluminescence (PL) properties of GOQDs and the rGOQDs samples were investigated. The results showed that compared to GOQDs, a blue to purple tunable PL of rGOQDs can be obtained by regulating the annealing temperature. The increase fraction of the newly formed isolated sp(2) clusters may be responsible for the observed tunable PL. (C) 2014 AIP Publishing LLC.
