Kyushu University delayed fluorescence OLED emitters explained

In December 2012 we posted about Japan's Kyushu University new rare-metal free fluorescent OLED emitter materials that achieve 100% emission efficiency. Now the International Society for Optics and Photonics (SPIE) released a new video featuring Kyushu's professor Chihaya Adachi. Following a rather long introduction into his lab and his own biography, professor Adachi explains their thermally activated delayed fluorescence (TADF) technology (also called hyperfluorescence).

Adachi says that are seeking a commercialization partner, and they still need to study the degradation mechanism and expand the emission spectrum. Towards the end of this video you can view a couple of prototype monochrome (green) panels that use their new emitters.
