本研究使用常見的發光染料作為共主體，以有效提升有機發光二極體元件的效率，並改善元件效率滾降(roll off)的現象。在使用磷光天藍光染料Bis(3,5-difluoro-2-(2-pyridyl)phenyl-(2-carboxypyridyl) iridium(III) [FIrpic]作為共主體，並以4,4’,4’’-tri(N-carbazolyl) triphenylamine (TCTA)為主體的黃光元件，在亮度10,000 cd/m2時，其能量效率由11.7 lm/W提升至15.4 lm/W，提升幅度為32%。在亮度1,000 cd/m2時，能量效率為26.7 lm/W，是目前以濕式製作黃光有機發光二極體的世界紀錄。此其元件效率的顯著改善，可歸因為：一、共主體有電子捕捉的特性，促使身為少數載子的電子，可以更有效注入，以與電洞的注入平衡，二、激子在共主體上產生，可避免過多激子在客體上產生所導致的焠熄，三、共主體的添加，產生了額外的效率有效的主客體能量傳遞路徑，四、此共主體與客體間，有良好的能量傳遞。此外，所謂最有效的共主體，將視主體而定，特別要依據共主體與主體彼此間的能階匹配而定。
