[OLED4-3] “Efficient Indium Phosphate based Quantum Dot Light Emitting Diode using Sol-gel processed Electron Transfer Layer”
キーワード:QLED, Quantum dot, Inverted structure, InP-QD
Here, we report an efficient indium phosphate (InP) based inverted red Quantum Dot-Light Emitting Diodes (QLEDs) by incorporating a sol-gel processed Mg-doped ZnO layer. The red InP-QLED with our sol-gel processed Mg:ZnO layer reveals a maximum EQE of 7.7% , which is significantly higher than the ZnO and Mg:ZnO nanoparticles layers. These results suggest that the sol-gel processed Mg-doped ZnO layer is relatively efficient in terms of performances.
