TADF closes gap to phosphorescence: efficient blue OLEDs

Published in the April 2014 issue of Nature Photonics, the group of Chihaya Adachi report on highly efficient blue OLEDs based on the novel thermally activated delayed fluorescence (TADF) concept (Efficient blue organic light-emitting diodes employing thermally activated delayed fluorescence). This is yet another important and equally impressive milestone in the OLED field, which puts these novel emitters on par with phosphorescence emitting molecules (at least with respect to their efficiency).

Along with the paper mentioned above, I express my thoughts about this development in a Nature Photonics News & Views feature. Read it here: Phosphorescence meets its match. I expect to see white TADF OLEDs coming in 2014.
