從過去單一金屬結構的研究中發現，貴金屬在小尺寸的情況下受激發的電子會有很高的機率耦合進表面電漿子共振模態之中，此一現象使得金屬螢光的波形可以藉由調控貴金屬的結構以及兩兩偶合關係來改變。

這次的實驗中利用大面積結構量測消散光光譜作為表面電漿共振訊號的依據，與螢光光譜行為進行對照，觀察此一螢光機制在大範圍偶合的結構是否適用，實驗中主要量測三種不同的薄膜利用化學方法所製做的最密堆積金顆粒膜，改變金顆粒的大小以及層數與使用熱蒸鍍的方式製作出來的金顆粒膜作為對照組進行比較。

從實驗中可以發現最密堆積的金顆粒薄膜結構中消散光譜與螢光光譜波形有很好的對應關係，因此可以利用改變金屬結構的消散光達到大面積可見光全波段的螢光，甚至可以利用多層結構的縱向耦合達到更長波長的應用。

In this work, we performed the photoluminescence and plasmon resonance of nanoparticle films. Using the extinction spectra as the basis of signals of plasmon resonance, and we compare the extinction and PL spectra. In the experiment we measure on three kind of nanoparticle films, close-pack gold nanoparticle films change the size and numbers of layer and deposited by using E-beam evaporator. We systematically observed simultaneous red shift in PL and extinction spectra with increasing particle size and confirm that L-mode resonance also contributed to the PL of the multilayer close-pack gold nanoparticle films. For Au nanoparticle film deposited by using E-beam evaporator, we observed blue shift of the photoluminescence peak (relative to the scattering peak).
