- Abstract
- We demonstrate the use of screen printing in the fabrication of highly efficient phosphorescent polymer organic light-emitting devices (OLEDs) based oil a green-emitting Ir(ppy)(3) and a host polymer PVK We incorporate PBD in the polymer host as an electron-transporting dopant and alpha-NPD as a hole-transporting dopant. The best screen-printed single-layer device exhibits very high peak luminous efficiency of 63 cd/A at a relatively high operating voltage of 17.1 V at the luminance of 650 cd/m(2). We observed the highest luminance of 24,000 cd/m(2) at 35 V. Due to the NO operating voltage, despite of the high peak luminous efficiency the peak power efficiency was found to be 12.2 lm/W at the luminance of 470 cd/m(2) (15.9 V). 2008 Elsevier B.V.
