Graphene QDs Raise OLED Brightness
The first graphene quantum dots, made with high-quantum-yield nanodots (obtained through graphite intercalation compound synthesis), have enabled luminance above 1,000cd/m² in OLEDs. Researchers at the Korea Advanced Institute of Science and Technology (KAIST) worked on the quantum dots, in which graphene replaces cadmium. Carbon has recently begun to be used as a replacement for cadmium; … Read more
