摘　　要：首先制备了结构为ITO/m-MTDATA(30nm)/NPB(20nm)/CBP:FIrPIC(10%,30nm)/5,6,11,12-tetra-phenylnaphthacene(rubrene)(xnm/Bphen(40nm)/LiF(0.8nm)/Al的器件。此器件效率降低,为提高效率,我们又制备了另一器件,其结构为ITO/m-MTDATA(30nm)/NPB(20nm)/rubrene(0.2nm)/CBP:FIrPIC(10%,30nm)/Bphen(40nm)/LiF(0.8nm)/Al。此器件亮度效率及色坐标均有所改善。此器件的最大亮度为14V时,10050cd/m2,最大效率为8V时,4.59(cd/A),7V时,1.89(lm/w)。1000cd/m2时的效率约为4.00cd/A(10V时,1.25lm/w)。当亮度由1354cd/m2变到10050cd/m2时,色坐标由(0.33,0.37)变到(0.34,0.37)。The structure of ITO/ m-MTDATA （30 nm）/NPB（20 nm）/CBP： FIrPIC（10% ,30 nm）/rubrene（x）/Bphen（40 nm）/LiF（0.8 nm）/Al was fabricated by using blue phosphorescent and yellow fluorescent matter. The device can give white light as x=1 nm. The maximum luminance and power efficiency of the WOLED are 4 464 cd/m^2 at 13 V and 2.058 cd/A at 5 V,1.29 lm/W at 54 V, respectively. The CIE of the device changes from（0.37,0.43） at 1556 cd/m^2 to （0. 35, 0.39） at 3 480 cd/m^2. Due to the bad efficiency,we made another device with structure of ITO/m-MTDATA （30 nm）/NPB（20 nm）/rubrene（0.2 nm）/CBP：FIrPIC（10% ,30 nm） /Bphen（40 nm）/LiF（0.8 nm）/Al. Its＇ maximum luminance and power efficiency are 10050 cd/m^2 at 14 V and 4.59 cd/A at 8 V,1.89 lm/W at 7 V, respectively. When the bright changes from 1354 cd/m^2 to 10 050 cd/m^2 ,the CIE of the device changes from （0.33,0.37） to （0.34,0.37）.
