雷射是光子積體電路的應用上的關鍵之一，隨著科技的進步，半導體製程的尺度逐漸縮小，所以對雷射的體積要求也逐漸縮小，當共振腔縮小至一個半波長的大小時，會受光學繞射的限制無法繼續縮小尺寸，而一種由金屬薄膜與週期性介電質結構組成共振腔的塔姆電漿子雷射可以突破繞射極限縮小雷射尺寸，但塔姆電漿子雷射往往需要在極低溫的環境下才能操作。為此本論文使用鈣鈦礦作為雷射的增益介質，其激子束縛能大於室溫熱擾動的特性，可以幫助塔姆電漿子雷射達成室溫下操作的可能性，但鈣鈦礦容易受空氣中的水氣與氧氣影響而降解，造成實際應用上的困難。而文獻表明多孔隙材料可以有效防止鈣鈦礦量子點受水氣影響，因此本論文將鈣鈦礦合成於金屬有機框架材料UiO-66的孔隙中，並置於金屬薄膜與布拉格反射鏡之間，透過光致發光量測系統分析。研究結果顯示，成功的從光譜圖中觀察到雷射共振腔的模態，並透過穩定性測試發現鈣鈦礦量子點保存在防潮箱中長達7個月左右仍保有相當的光致發光的強度。

This research observed the laser cavity modes of perovskite quantum dots (PQDs) in the interface between a gold thin film and a distributed Bragg reflector (DBR) through the PL spectrum. We embed a layer of PQDs in the boundary between the metal thin-film and the periodic dielectric structure to achieve the coupling between the excitons and the optical Tamm state at the interface. Using the characteristic of PQDs, which exciton binding energy is greater than the thermal kinetic energy of ~26meV at room temperature, as a laser gain medium, can help us achieve laser operation at room temperature. And we have successfully improved the stability by synthesizing PQDs in a metal-organic framework (MOF). PQDs@UiO-66 can effectively resist moisture and maintain the same photoluminescence intensity for more than 90 days through the stability test.
