本論文探討使用兩階段的沉積法成長CH3NH3PbI3微米晶體，成長完的晶體使用掃描式電子顯微鏡觀測其形貌。光譜儀用來監測CH3NH3PbI3其光致螢光於雷射持續照射下的變化情形。穿透光譜用來檢測CH3NH3PbI3照光前與照光後是否有任何材料結構上的變化。
我們發現剛成長出來的CH3NH3PbI3其螢光波峰波長位置約位在770 nm奈米處，且在一般空氣施以高強度的雷射光照射(634 mW cm-2)，它的光致螢光強度有越來越弱的趨勢。然而於有氧無水氣的環境下施以低強度雷射光照射(210 mW cm-2)，它的光致螢光強度卻漸升之後又漸弱，在同樣的雷射功率下，我們在無氧無水氣的環境下重複同樣的實驗，發現光致螢光強度沒有漸升的現象。
最後於有氧無水氣與無氧無水氣的環境執行時間解析發光光譜的量測，發現氧氣對於鈣鈦礦照光之後的反應有著非常顯著的影響，於內文中將有詳細的介紹，藉由本研究，我們希望能對鈣鈦礦於不同環境條件下(照光強度的強弱或氧氣的有無)產生的光反應有更深的了解，並期望此對製作穩定的鈣鈦礦元件有幫助。

A two-step crystal growth method was introduced to prepare high optical quality perovskite CH3NH3PbI3 microcrystals. The morphologies of these microcrystals were observed by scanning electron microscopy (SEM). To monitor the luminescence evolution of CH3NH3PbI3 microcrystals with laser irradiation under different ambient conditions, in-situ photoluminescence (PL) and time-resolved PL (TRPL) systems were utilized. An optical absorption spectra measurement was employed to study the structure/phase changes of microcrystals after laser irradiation.
We found the PL peak emission wavelength of as-prepared CH3NH3PbI3 microcrystals was centered at 770 nm. Under high power density (634 mW cm-2) irradiation in the air, the PL peak intensity of CH3NH3PbI3 microcrystals gradually decreased. However, under low power density (210 mW cm-2) irradiation in a relative low humidity environment with Oxygen, its PL peak intensity slowly increased first and then decreased eventually. We also conducted the controlled experiment, which was in a relative low humidity environment with no Oxygen, to verify the effect of Oxygen. The PL intensity shows a monotonically increases as a function of the measured time.
Lastly, we compared the time-resolved photoluminescence (TRPL) results between two environments (with or without Oxygen). We found that Oxygen plays an important role in the light-induced reaction of CH3NH3PbI3 microcrystals. In this study, we hope to give an in-depth understanding on the light-induced reaction of CH3NH3PbI3 microcrystals. We also hope this study can help fabricate more stable perovskite device.
