Researchers have demonstrated an OLED that uses singlet fission to boost the percentage of excitons created per pair of electrical charges to over 100 percent. This increase of light-producing excitons when one singlet exciton is split into two triplet excitons through singlet fission results in a stronger emission intensity and is promising for the development of high-intensity near-infrared OLEDs for biological and communications applications.
