2019 journal article

Realization of high-efficiency fluorescent organic light-emitting diodes with low driving voltage

Nature Communications, 10(1).

By: A. Salehi n, C. Dong n, D. Shin n, L. Zhu n , C. Papa n, A. Thy Bui  n, F. Castellano n , F. So n 

TL;DR: It is demonstrated organic molecules with a large singlet-triplet splitting can achieve efficient EL at voltages below the bandgap voltage, and a blue fluorescent organic light-emitting diode having a power efficiency higher than some of the best thermally activated delayed fluorescent and phosphorescent blue organic Lightemitting diodes is demonstrated.
