- Recently, most studies concerning inorganic quantum dot (QD)-polymer hybrid LEDs have been concentrated on the structure with multiple layers1), 2) and CdSe materials for color reproduction such as blue, green and red from the light source has been widely used. Because Cd, however, is one of six substances banned by the Restriction on Hazardous Substances (RoHS) directive and classified into a hazardous substance for utilization and commercialization as well as for use in life, it was reported that the use of CdSe is not suitable to fabricate a photoelectronic device. In this work, a novel, simple and facile technique is introduced for the synthesis of eco-friendly ZnO–graphene quasi-core–shell quantum dots utilizing graphene quantum dot to overcome the toxic property of Cd. Also, we reported optical and structural properties of the hybrid quantum dots and the performance of LEDs.
