文摘
- •
Al nano-concave arrays with different interpore distance (Dc) were prepared.
- •
PL of ZnO thin films deposited directly on the Al nano-concaves were studied.
- •
The effect of 10 nm Al2O3 spacer on PL emission from ZnO thin films was analyzed.
- •
Plasmonic enhancement of the PL emission was dependent on the Dc and the spacer.
- •
The highest 9-fold enhancement was obtained for the Al/ZnO sample with Dc ∼333 nm.
