Open questions on the photophysics of thermally activated delayed fluorescence
Julien Eng, Thomas J. Penfold
Abstract
The process of thermally activated delayed fluorescence (TADF) converts non-radiative triplet states into emissive singlet states. Herein we outline the fundamentals of TADF, some of the recent progress in understanding the key material properties responsible for promoting TADF and finally discuss some remaining challenges for the potential applications of this phenomenon.
