【 摘 要 】

We experimentally demonstrate the strongly enhanced photoluminescence of the fluorescent molecules on the metamaterial mirror. The matematerial mirror can optimize the reflection phase to provide a large electric field for the 20-nm-thick active layer. Compared with the smooth gold plate, the experimental result shows a nearly 45 times enhancement.
