White top-emitting organic light-emitting devices (TEOLEDs) were fabricated on a glass substrate with metal/organic multilayer of (Ag/Alq_3)_2 (Alq3 is tris-(8-hydroxyquinoline) aluminum) as cathode. White TEOLEDs with high efficiencywere obtained due to the microcavity effects.Andthe (Ag/Alq_3)_2 cathode,which adjusted the optical characteristics of the devices, played an important role. In addition, Alq_3―Ag―Alq_3multilayer could work as a buffer layer, which would simplify the process of encapsulation for devices.We also calculated the electroluminescence spectrum of devices encapsulated with Al_2O_3 (150 nm) and Al_2O_3(75 nm)/ZrO_2(75 nm). And the results indicated that the CIE coordinates is almost the same between with and without encapsulating.
