Highly Efficient and Stable Red Phosphorescent OLED Using Platinum Complex as Guest Material

摘要

We demonstrate a highly efficient and stable red phosphorescent OLED using a platinum complex. The OLED exhibits a maximum external quantum efficiency of about 20% with CIE = (0.66, 0.34) and an expected half lifetime of about 10,000 h from an initial luminance of 1000 cdlm~2.
