文摘
- •
The light extraction behavior and mechanisms of ZnO nanotubes LEDs have been investigated.
- •
The influences of ZnO nanotubes configurations have been studied.
- •
The LEE over the whole visible spectrum has also been demonstrated.
- •
An optimization of ZnO nanotubes geometries which leaded to more than four times enhancement of LEE has been presented.
