在本文中我們將探討量子點所激發出光子與奈米共振腔間的關係，研究其光子動態行為，為了增強自發輻射強度與耦合效率。在本研究中光源為膠體硒化鎘/硫化鋅量子點，量子點本身具有獨特的發光特性與機制如高發光效率、寬吸引光譜、化學合成可大量生產等優點，但也有受激發光時會因歐傑程序產生閃爍不穩定的缺點，除了從化學與材料上改進外，本研究我們以量子點在空間與頻率上的耦合增強衰逝速率也可降低閃爍的發生。
在膠體量子點與矽奈米碟型共振腔的耦合的研究中，我們以460nm波長的皮米脈衝雷射做光源，在半導體製程的矽奈米碟型共振腔上方的量子點使其耦合至奈米共振腔中，在高濃度量子點的旋鍍下，可以從掃瞄式共軛焦顯微鏡及光激發光譜量得雷射訊號，隨著濃度降低時，高效率矽單光子源也可以達成，皆在半導體製程產生平整的矽奈米碟型共振腔使得有高品質因子進度Purcell效應(6倍)提升，也是光子耦合之速率變快的因素。
另外，我們也研究膠體量子點與金屬間的交互作用。由於繞射極限的因素，光很難被局限於數百奈米以下，而金屬可以超越此限制，可將光場局限於數十奈米的金屬奈米粒子，從Purcell 效應的角度，縮小光場體積也可以提升耦合速度。在這一部分，我們也証明將量子點放置在化學合成之銀奈米線與鍍金之原子力顯微鏡的針尖之中，動態的量測從光譜得到共振腔模態的強度增益，且隨著針尖越來越靠近下，光子耦合速率變快，耦合效率亦明顯的提升至76%。
