The color purity of organic light-emitting devices is restricted mostly by the intrinsic character of emitting material
but optical cavity can improve the color purity via changing the structure of devices. In this paper
we demonstrated that highly saturated homo-chromaticity light can be obtained by adjusting the thickness of organic layers. Organic top-emitting electroluminescent devices were fabricated in this method
the structure of the device was Ag/m-MTDATA/NPB/DPVBi/Alq
