英文摘要：

To meet the needs of large - area solid - state lighting and full - color display, the research aims at achieving the effi cient and chromaticity stable top - emitting white organic light emitting diodes. The research methods combine the simulations with experiments. The optical simulations are based on the optical transfer matrix method and electromagnetic theory, while the top - emitting white organic light emitting diodes are fabricated by vacuum evaporation and the photoelectric properties of the de vices are measured. By determining materials, thicknesses and structures of transport layers, optimizing the luminous efficiency, gradually developing the structures of emitting layer, the luminous efficiency and the color quality of the devices are improved. It＇ s concluded that the transport layers based on an electrical balanced P - I - N structure and the emitting layers based on a blue/red/blue sandwiched structure are able to achieve efficient and chromaticity stable top - emitting white organic light emitting diodes.
