碩士 === 國立清華大學 === 光電工程研究所 === 94 === A new, low-cost approach for enhancing light extraction of organic or inorganic light emitting devices by texturing emitting surfaces was studied in this research. The surface is textured either by nanoimprinting or nanocasting technologies which use Anodic Aluminum Oxide templates (AAO templates) as molds. Unlike other nanoimprinting molds AAO templates have advantages in easy fabrication, controllable pore sizes and large printing area. Polydimethyl siloxane (PDMS) is one kind of common polymers as nanoimprinting materials. Fluidity and low surface energy make it easy to conform to the surface and demold. Therefore, it is suitable for casting fine structures.
