- Abstract
- Multilayered organic light-emitting diodes (OLEDs) were fabricated by using the new fluorine derivatives end-capped with arylaminofluorenylethylenes as dopant materials. The device structure was ITO/NPB/15% blue dopants doped in MADN/Bphen/Liq/Al. Among those, a device shows the maximum luminance of 40800 cd/m(2) at 12 V, the luminous efficiency of 12.8 cd/A at 20 mA/cm(2), power efficiency of 9.13 lm/W at 20 mA/cm(2) and CIEx,y coordinates of (x = 0.188, y = 0.372) at 8 V.
