Abstract

White emission from polymer light-emitting diodes (PLEDs) is demonstrated by spin-casting polymer blends from solution containing poly(9,9-dioctylfluorenyl-2.7-diyl) (PFO) and tris (2,5-bis-2'-(9',9'-dihexylfluorene) pyridine) iridium (III), Ir(HFP)₃. The white electrophosphorescence PLEDs exhibit luminance of 1.2 x 104 cd/m² at 17 volts and luminous efficiency of 4.3 cd/A at current density of 5.2 mA/cm². Because a single semiconducting polymer, PFO, was used as the common host for red, green and blue emission, the color coordinates, the color temperatures and the color rendering indices of the white emission are insensitive to the brightness, applied voltage and applied current density.
