- Abstract
- Three-component blend system based on polyfluorene derivative (SK32®), substituted polyacetlyene (PTMSDPA) and iridium complex (red dopant) were fabricated as a single emitting layer for white OLED. The two polymers and iridium complex were well mixed to provide transparent films. Its electro-optical properties were investigated in terms of emission color, brightness, and luminescence efficiency. The optimal weight ratio for white emission was 100 (SK32®): 5 (PTMSDPA): 0.5 (red dopant). The color coordination at this ratio was (x = 0.33, y = 0.33), completely matching to white color. The luminance was 831 cd/m2 at 17 V, its current efficiency was estimated to 1.15 cd/A at 9 V and the maximum power efficiency reached 0.44 lm/W at 7 V.
