Paper Abstract

We demonstrated green to red color-tunable OLED based on DNA/PAn/Ru(bpy)3 2+ complex (hole transport layer) and tris(8-hydroxyquinolinato)aluminium (Alq3: electron transport layer). The emission color of the OLED was controlled by applied voltage. At low applied voltage, the green emission dominated by Alq3 was observed. The emission color was changed from green, yellow to red with a strong contribution of red emission of Ru(bpy)3 2+ as voltage increased. This multi color emission phenomenon would be attributed to the shift of the carrier recombination zone depending on applied voltage.
