Light‐emitting electrochemical cells have been fabricated for the first time from graphene quantum dots (GQDs) sandwiched by ITO and Al electrodes, to display a broad and strong white emission. The GQDs have been fabricated in gram scale from electrochemical exfoliation of graphite and studied in electrochemiluminescence to gain insight into their optoelectronic characteristics. It is anticipated to use the GQDs in lighting applications. More information can be found in the Full Paper by Z. Ding et al. on page 15892.
