Kyushu University Claims OLED Breakthrough

Kyushu University Claims OLED Breakthrough Jun 1, 2014 01:11 Tetsuo Nozawa, Nikkei Electronics The newly-developed assistant dopant and the mechanism of light emission. Each color is produced by a single dopant. The fluorescent dopant materials used for devices and the spectra at the time of light emission The Center for Organic Photonics and Electronics Research (OPERA) of Kyushu University developed an OLED device that emits light by using a fluorescent material with an internal quantum efficiency of 100%. The device was realized by using the "thermally activated delayed fluorescence (TADF)," which OPERA has been developing, as an assistant dopant and dispersing it in the light-emitting layer of a conventional fluorescent OLED device. Compared with the previous TADF, the new technology enables to make a material and device with a more versatile and easier method and impr...
