| Abstract: | A new material group, DPVBi and Bphen, are presented to form electroplex with their efficient white emission in a p-i-n OLED. The experimental results bear out that the interracial phenomenon between DPVBi and Bphen originates from electroplex but not exciplex. By introducing p-i-n structure, the white OLEDs exhibits relatively high peak luminance of 9 050 cd/m2, and power efficiency of 2.63 lm/W. Further more, the Commission Interna-tionale De l'Eclairage coordinates of resulting emission varies gradually with increasing forward bias. Consequently, a consistent white color is obtained. It affords more opportunities in facilitating the fabrication process of white OLEDs. |
