Blue phosphorescent OLED with EQE over 34% using low refractive index electron transporting layer |
| 초록 |
In this study, we demonstrate a blue OLED with the EQE of 34% and power efficiency of 79.6 lm W-1 using low refractive index electron transporting layer which are the highest efficiencies ever reported in blue OLEDs. In additon, we quantitatively calculated maximum achievable outcoupling efficiencies according to change of refractive indices, which can be used to estimate the achievable outcoupling efficiency of OLEDs without fabrication. The simulation indicates that EQE over 60% can be achievable in PhOLEDs if refractive indices of consisting organic materials’ are close to 1.5. |
