【 摘 要 】

The project objective is to demonstrate high efficiency white emitting OLED devices with a target luminous efficiency between 100 1m/W and 150 1m/W with integrated microcavity structure and down conversion phosphors. The main focus of this work will be on three areas: (1) demonstration of a 2X reduction in OLED device operating voltage by employing the appropriate dopants in the carrier transporting layers; (2) demonstration of a 3X light out-coupling efficiency enhancement by incorporating microcavity structure in the OLED devices; and (3) demonstration of a 2X down-conversion efficiency enhancement (from blue to white) using phosphors.
