EurekAlert November 11, 2020 Inspired by a class of molecules previously used for biomedical imaging researchers in Canada developed two new organic compounds with emission peak at a wavelength of 840 nm. The OLED showed a quantum efficiency of 3.8%. The latter corresponds to the percentage of electrons circulating throughout the device, electrons which are then converted into useable light. The efficiency is more than three times higher than that of the best previously reported fluorescent OLEDs in this spectral range and approaches that achievable with the best platinum‐containing phosphorescent emitters. The device has possible applications in biomedicine, facial recognition, […]
