~Clue to development of light-weighted, flexible, high-contrast lighting. An international joint research group succeeded in developing a novel thermally activated delayed fluorescence (TADF) material which displays emission of light in colors from green to deep-red through Intersystem Crossing from the singlet to the triplet excitons, a world first. The results will contribute to R&D in white TADF light emitting devices for indoor and outdoor use through combination with TADF materials that emit light in shorter wavelengths (deep blue to yellow).

Over the last few decades, research on organic light-emitting diodes (OLEDs) has greatly advanced...
