Based on the red and green/blue light emitting layer
six white phosphorescent OLEDs are fabricated by using Ca/Al/Mg alloy as cathode
and the effects of different proportion of Ca/Al/Mg alloy on OLEDs are researched by changing the doping ratio of Mg. The device structures are as follows: ITO/MoO
25). The experiment results show that the cathode with Mg mass fraction of 15% has good electron injection characteristics which can effectively improve the light-emitting characteristics of the device. The maximum brightness is 1 504 cd/m
2
the maximum current efficiency is 14.3 cd/A
and the color coordinates is close to (0.46
0.42).
