By adjusting the thickness of P SAL, the CIEx,y of devices, which utilize 2, 7-Di-pyrenyl-9, 9-spiro-bifluorene （DPSF） as emitting layer, changes from （0.16, 0.50） to （0.18, 0.37）. The maximnum current efficiency of 7.1 cd/A is acquired under 4.5 V with an increasing luminance of 139 cd/m^2. Compared with adjusting the total thickness of organic layer, it is more beneficial for achieving blue TEOLEDs with high efficiency.展开更多
