PHOSPHORESCENT OLED HAVING DOUBLE HOLE-BLOCKING LAYERS |
摘要 |
<p>An organic light-emitting device has a first hole-blocking layer in contact with a phosphorescent light-emitting layer and a second hole-blocking layer in contact with the first. The material in the first hole-blocking layer has a triplet energy greater than the host of the phosphorescent layer and the material in the second hole-blocking layer has a triplet energy higher than the dopant in the phosphorescent layer. Both hole-blocking materials have lower HOMO energies than the host of the phosphorescent light-emitting layer</p> |
