| 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6.6cd/A和最大功率效率3.21lm/W,此时亮度为10520cd/m2,对应的CIE坐标为(0.3186,0.3520)。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 ( AND ),2,5,8,11-tetra-butyl-perylene(TBPe) and 4- ( Dicyanomethylene)-2-t-butyl6-(1,1,7,7-tetramethylj-ulolidyl-9-enyl)-4H-pyran(DCJT B).By examining the device characteristics 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(ηL) and power(ηP) efficiencies,which are 6.6 cd/A and 3.21 lm/W at luminance of 10 520 cd/m2 with CIE coordinates of (0.318 6,0.352 0).The different color of devices can be obtained by changing doping concentration of DCJTB. |
