Abstract: 本實驗使用高溫注入法合成鈣鈦礦量子點(perovskite quantum)作為發光層,再結合上下布拉格高反射鏡,形成垂直共振型光二極體結構。透過365 nm 發光二極體作為激發光源,照射鈣鈦礦量子點,藉由共振腔所產生的珀塞爾效應(Purcell effect),使鈣鈦礦量子點光致發光光譜的半高寬縮減。研究主要分為兩部分:第一,調控鈣鈦礦前驅物反應物值比例,產生藍、綠、紅溶液。有系統的研究藍、綠、紅鈣鈦礦量子點相關之材料及光學分析,並設計與製作所對應之不同發光波段的布拉格高反射鏡高反射鏡,並分析其穿透吸收光譜。第二,將三原色鈣鈦礦量子點滴至高反射鏡上,再將另一片高反射鏡蓋上,在下面放置365 nm 發光二極體,激發出鈣鈦礦量子點的螢光,光纖可以收到白光共振腔發光二極體的光譜,並將該光譜激發螢光蛋白質,用來檢測癌細胞的相關應用。最後,我們預期本研究結合藍、綠、紅鈣鈦礦量子點之垂直共振型光二極體結構,將可作爲未來新穎白光元件之應用。
In this experiment, a high-temperature injection method was used to synthesize a perovskite quantum dot (perovskite quantum) as a light-emitting layer, and a vertical resonant-type photodiode structure was formed by combining upper and lower Distributed Bragg Reflector. The 365 nm LED is used as an excitation source to illuminate the perovskite quantum dots, and the half-height of the perovskite quantum dot photoluminescence spectrum is reduced by the Purcell effect generated by the resonant cavity. The research is mainly divided into two parts: First, the ratio of the reactant values of the perovskite precursor is regulated to produce blue, green and red solutions. Systematic study of blue, green, and red perovskite quantum dot related materials and optical analysis, and design and fabrication of different high-intensity Bragg high-reflector high-reflection mirrors, and analysis of their breakthrough absorption spectra. Second, the three primary color perovskite quantum dots are dropped onto the high-reflection mirror, and another high-reflection mirror is placed thereon, and a 365 nm light-emitting diode is placed underneath to excite the fluorescence of the perovskite quantum dots, and the optical fiber can be received. The white light cavity illuminates the spectrum of the diode and excites the spectrum to detect fluorescent proteins for use in detecting cancer cells. Finally, we expect this study to combine the vertical resonance type photodiode structure of blue, green, and red perovskite quantum dots, which will serve as a future novel white light component.
