Luscombe, Christine C.K.L.Huang, Yunping2022-04-192022-04-192022-04-192022Huang_washington_0250E_23887.pdfhttp://hdl.handle.net/1773/48527Thesis (Ph.D.)--University of Washington, 2022Optical engineering plays a crucial role in optoelectronic and communication devices, regarding efficiency, quality, and applications of the final devices. It consists of two components: design and manufacture of devices and development of materials. The former emphasizes the architecture of a device and the precision in its fabrication, while the latter focuses on tailoring materials’ optoelectronic properties to enable a specific application. In this contribution, we focus on the optimization of light converting materials, organic phosphors and quantum dots, bridging the gap between performance and stability at low costs and thus accelerating their commercial adoptions. On the other hand, these two types of materials enable solution processing of devices, which simplifies device manufacture and meanwhile empowers the development of novel device architectures.application/pdfen-USCC BY-NC-SAC-H activationGreen chemistryOrganic dyePerovskite nanocrystalPhotoluminescence quantum yieldSurface chemistryMaterials ScienceMaterials science and engineeringThesis
