本實驗以常溫過飽和再結晶法製備鈣鈦礦量子點，並針對其表面缺陷進行探討及修飾，以提升螢光量子產率(QY)為重點，再利用以優化之鈣鈦礦量子點應用於離子感測及LED元件製備上。本研究主要會分為兩部分進行討論，第一部分會探討鈣鈦礦量子點表面修飾的部分，而第二部分會將此量子點應用於離子感測及LED元件。
　　第一部分：本實驗之鈣鈦礦量子點之製備方法不同於以往需於低水氧含量的環境或手套箱中，並以常溫過飽和再結晶法在一般大氣環境下即可成功製備鈣鈦礦量子點，不僅如此，在進行表面缺陷修飾後可大幅提升螢光量子產率(QY)從30.35 %至83.34 %。再經過HR-TEM、XRD、FTIR及PL lifetime等儀器測量優化過之鈣鈦礦量子點的光學性質及表面進行分析，並進行機制探討。
　　第二部分：利用已表面修飾過後之鈣鈦礦量子點進行後續應用，第一種應用會先以此量子點於有機溶劑相進行離子感測實驗，確認量子點對離子專一性反應並建立光學變化與待測物濃度間的線性關係，再利用光學儀器並分析確認其機制後，最後利用民生用油進行示範性的銅離子感測實驗。第二種應用是同樣將此優化過之鈣鈦礦量子點與高分子polystyrene混和後，將其鈣鈦礦量子點膠體溶液滴於市售紫外光基板上，再接上電流供應器後可成功製成一綠光LED元件。

　　In the present work, we demonstrate a facile supersaturated recrystallization method under room temperature to synthesize perovskite quantum dot (PQD) by using two capping agents, which are oleic acid (OAc) and oleylamine (OAm). This Supersaturated recrystallization method is facile synthesis and cost-effective. In the synthesis process, there is a formation of hydrogen bonds between the protons of the amine group and the Br- ions on the surface. So, this will assist to reduce surface defect formed on the surface and lead to enhanced the quantum yield from 30.35 % to 83.34 %. To understand this enhanced mechanism, we explored and verified through FTIR and XPS spectroscopic methods.
　　Furthermore, the superior optical properties of PQDs give promising route to use in different applications. In this work, we demonstrate two different applications, for the ion-sensing and LED device applications. In the former application, using analyte which shows specific binding to the PQD and we proceed for sensitivity quenching experiment in order to get the limit of detection. For the ion sensing application of PQDs, we performed in edible oil and vacuum pump oil for the fast detection of Cu2+ ion. For the second application, this PQDs were used for the LED devices. In this application, mixing a PQD with polystyrene can form a thin film on the commercial ultraviolet chips which successfully show the bright green color by connecting the power supply.
