摘要：

Color control and white emission of organic light-emitting device by external light irradiation was achieved by employing an opto-electronic gate out of titanyl phthalocyanine and two emission layers that emit complimentary color of each other. The recombination site in the device can be tuned by intensity of external light. Without laser irradiation, holes and electrons recombine mainly at the blue emission layer, thus only a blue emission is observed. On the other hand, electroluminescent peak around 560nm increases by laser irradiation: the emission color is continuously and reversibly varied from blue to orange via white.
