摘要

近年來有機鈣鈦礦半導體成為太陽能領域與平面發光元件的核心，在其眾多光電領域也都有重要的應用空間，例如高效率鈣鈦礦螢光量子點(quantum dot, QD)。本文將以低溫溶液法進行製備有機鈣鈦礦量子點及將對其材料特性做進一步研究及分析。所製作的有機鈣鈦礦量子點其結構將以X光粉末繞射儀(x-ray diffractometer)、光激發光量測系統(photoluminescence)及穿透式電子顯微鏡(transmission electron microscope)進行分析，藉以研究材料製備方式對有機鈣鈦礦量子點性質的影響及其影響的程度，研究亦發現有機鈣鈦礦量子點會因為分散溶液的極性不同明顯影響存放時間及其穩定性。

Recently, organic perovskite materials received a considerable boost in photovoltaic cells, light emitting diodes and other optoelectronics, such as quantum dots (QDs). This study made every effort to prepare organic perovskite quantum dots using low-temperature processes and analysis their material characteristics. To know the relationship between fabrication method and the resulting QDs, x-ray diffractometer, photoluminescence meter and transmission electron microscope were perform to observe them. The results showed the storage and stability of QDs were significantly affected by the polarity of dispersion solutions.
