The optimized parameters are 3 minutes process time, 1.2 M ammonia, and 300?C post-annealing with 30 minutes which results in the quantum dots of 2.5 nm with high performance of crystallization. The second part is about the fabrication of narrow band pass filter, NBPF, with spacers including quantum dots. We successfully fabricate QDs-NBPF with the 3, 4, 5 pair number by Ion-Beam Sputtering Deposition and spin coating. And then with the 325 nm He-Cd laser pumping, the transmission of QDs-NBPF with 3 pairs, 4 pairs and 5 pairs at the center wavelength are 152.2 %, 418.3 % and 534.0 %, respectively. Finally we calculate the equivalent extinction coefficient k of the spacer of the QDs-NBPF by fitting the transmission intensity on the center wavelength. en_US DC.subject 量子點 zh_TW DC.subject 窄帶濾光片 zh_TW DC.subject 硫化鎘 zh_TW DC.title 量子點窄帶濾光片 zh_TW dc.language.iso zh-TW zh-TW DC.title Narrow band pass filter with the spacer including quantum dots en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
