Herein, we demonstrate that rapid thermal annealing allows achieving close-to-one photoluminescence quantum yield while preserving the transparency of rare-earth nanocrystal films, which further enables their integration with nanophotonics. The combination with periodic arrays of aluminum nanodisks that support collective plasmonic resonances leads to enhanced directional emission.
在此，我们证明了快速热退火可以在保持稀土纳米晶薄膜透明度的同时实现接近 1 的光致发光量子产率，这进一步使它们能够与纳米光子学集成。与支持集体等离子体共振的铝纳米盘周期性阵列的结合导致了增强的定向发射。
