摘要：
Top-emitting organic light-emitting devices with different-thickness top Ag cathodes were fabricated. The tris (8-hydroxyquinoline) aluminium based device with a 23 nm thick Ag cathode shows a maximum efficiency of 11.1 cdA(-1) and the brightness of the device can reach 560 cdm(-2) at 4V. The blueshift of the resonant wavelength (RW) in the devices with increasing thickness of the top Ag cathode was observed. The theoretical simulation was described by a model based on the Fabry-Perot microcavity structure. The results indicated that both RW and the efficiency of the devices are Ag thickness dependent.
