Electrical and optical analyses of tandem organic light-emitting diodes with organic charge-generation layer
The electrical and optical properties of tandem organic light-emitting diodes (OLEDs), in which a fluorescent and phosphorescent emitting units are connected by an organic charge-generation layer (CGL), were experimentally analyzed.To investigate the internal properties of the tandem OLEDs, we fabricated and compared two single, two homo-tandem, an
