Singular wavelength dependence on the sensitization of lanthanides by graphene quantum dots†
In this manuscript, we study the sensitization of Tb3+ ions by the excited state of GQD. We found that Tb3+ cations can bind to GQDs and display photoluminescence. Excitation dependent experiments show that the Tb3+ emission is stronger at shorter excitation wavelengths, which is likely due to pseudo-isolated small aromatic moieties produced during the synthesis of the GQDs.
