摘要

通过在发光层ADN∶TBPe∶DCJTB中改变DCJTB的掺杂浓度

得到了一种高效的白光OLED器件。考察了同一掺杂浓度TBPe下不同浓度的DCJTB的器件性能

发现当DCJTB掺杂浓度为1%(质量分数)时

器件获得最大电流效率6.6 cd/A和最大功率效率3.21 lm/W

此时亮度为10 520 cd/m

对应的CIE坐标为(0.318 6

0.352 0)。通过改变DCJTB浓度

能够获得不同的器件颜色。

Abstract

A highly efficient white organic light-emitting device could be achieved by changing doping concentration in the emissive layer of the device containing 9

10-di-(2-naph-thyl)anthracene(ADN)

11-tetra-butyl-perylene(TBPe) and 4-(Dicyanomethylene)-2-t-butyl-6-(1

7-tetramethylj-ulolidy1-9-enyl)-4H-pyran(DCJTB).By examining the device chara-cteristics of uniformly doped devices with varying dopant concentration

it is found that the device with the doping concentration(mass fraction) of 1% DCJTB gains the maximum current(

) and power(

) efficiencies

which are 6.6 cd/A and 3.21 lm/W at luminance of 10 520 cd/m

with CIE coordinates of (0.318 6

0.352 0). The different color of devices can be obtained by changing doping concentration of DCJTB.
