Unified Framework for Photophysical Rate Calculations in TADF Molecules [PDF]
Journal of Chemical Theory and Computation, 2021 One of the challenges in organic light emitting diodes research is finding ways to increase device efficiency by making use of the triplet excitons that are inevitably generated in the process of electroluminescence. One way to do so is by thermally activated delayed fluorescence, a process in which singlet excitons undergo up-conversion to singlet ...
