| 摘 要： | 采用双发光层双主体结构,制备了高效稳定的白光有机电致发光器件(WOLED)。其中蓝光层是TBADN:3 wt%DSA-Ph,红光层是[TBADN:Alq3]:1 wt%DCJTB,通过改变红光层中Alq3和TBADN的掺杂比来调节器件的发光效率和颜色。当[TBADN:Alq3]为75∶25时获得了效率最高、色度好和性能稳定的白光,在20 mA/cm2时器件的发光效率为6.27 cd/A,CIE色坐标为(0.364,0.348)。当电流密度为200 mA/cm2时,发光效率仍能保持在6.15 cd/A,色度坐标为(0.344,0.344)。由于在[TBADN:Alq3]双主体结构中,TBADN具有双极性,从而改善了器件中载流子的平衡及其在发光层中的分布,进而提高的器件的性能。

| Abstract: | An efficient and stable white organic light-emitting device(OLED) with dual emission layer consisting of cohost system is demonstrated.The blue-emitting layer is composed of fluorescent dye DSA-Ph doped into single host TBADN (TBADN:3 wt% DSA-Ph) while the red-emitting layer is fluorescent dye DCJTB doped into cohost system consisting of TBADN and Alq3([TBADN:Alq3]:1 wt% DCJTB).The device luminous efficiency and CIE color coordinates could be adjusted by altering the ratio of TBADN to Alq3 in the red-emitti... |
