摘要：
In this study, we developed hyperfluorescence-based full fluorescent white organic light-emitting diodes by doping blue and yellow fluorescent emitters in the blue thermally activated delayed fluorescent emitting layer. The blue thermally activated delayed fluorescent emitter acted as sensitizer for energy transfer to the fluorescent blue and yellow fluorescent emitters. The hyperfluorescence emission of the fluorescent emitters produced two white color emissions with a color coordinate of (0.26, 0.32). In addition, the fluorescent white organic light-emitting diodes exhibited a high external quantum efficiency of 13.0%. (C) 2018 The Korean Society of Industrial and Engineering Chemistry.
