摘要

获得了一种基于电致激基复合物的高效率白光有机电致发光器件

采用p-i-n结构

有效地降低了器件的工作电压。器件的最大亮度为9050cd/m

最大功率效率为2.63lm/W。随着电压的增加

器件的CIE色坐标一直处于白光区域。

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 interfacial 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/m

and power efficiency of 2.63 lm/W. Further more

the Commission Internationale 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.
