三原色鈣鈦礦量子點於垂直共振腔面射型雷射之光學特性研究

Abstract

本論使用高溫注入法合成鈣鈦礦量子點(perovskite quantum)，再與帶通濾波片作為垂直面形共振腔，做為結合。在這當中鈣鈦礦量子點作為發光增益介質，透過355 nm 脈衝雷射激發雷射。實驗分為三大類，實驗一:調控鈣鈦礦的反應物比例做出藍、綠、紅溶液，各別做材料分析以及光學分析，實驗二:將鈣鈦礦量子點旋塗至布拉格反射鏡上，再將另一片帶通濾波片蓋上，形成垂直腔面發雷射（Vertical-Cavity Surface-Emitting Laser）以355 nm 脈衝雷射激發雷射，實驗三:將藍、綠、紅色鈣太礦塗至於帶通濾波片試做出白光雷射In this work, we uses hot injection to synthesize perovskite quantum dots, and then combines with high-reflection Bragg mirrors as vertical-surface resonant cavities. In this case, the perovskite quantum dot acting with gain medium and excites the laser through a 355 nm pulsed laser. The experiment is divided into three categories. Experiment 1: The proportion of reactants for controlling perovskite is made into blue, green and red solutions, and each material is analyzed and optically analyzed. Experiment 2: Spin perovskite quantum dots on Bragg mirrors. On the other hand, another Bragg mirror is covered to form a Vertical-Cavity Surface-Emitting Laser to excite the laser with a 355 nm pulsed laser. Experiment 3: By using blue, green and red perovskite quantum dot and the high-reflection Bragg mirror ,and try to make a white light laser
