Abstract
We demonstrate the use of screen printing in the fabrication of single-layer organic-light-emitting devices (OLEDs). The organic layer is a single-layer of polystyrene, in which we incorporate rubrene for orange emission and α-NPD, DPVBi for blue emission. An appropriate mixing of the two colors produced white emission by incomplete Förster energy transfer. We showed the role of each constituent, α-NPD, DPVBi and rubrene in the emission characteristics of OLEDs. The turn-on voltage of screen-printed white OLEDs was about 10 V with maximum brightness and luminous efficiency up to 1300 cd/m2 and 9 cd/A, respectively.
