【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9 050 cd/m2,最大功率效率为2.63 lm/W。随着电压的增加,器件的C IE色坐标一直处于白光区域。更多还原

【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/m2,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.更多还原
