| Outline of Final Research Achievements |
This project developed a method of replication of nanostructures by direct heating surface of roller mold. We designed and assembled a roller replication system, in which 100-mm-wide mold is setup and 100W laser is focused and irradiated on the surfaces of the optical polymer film. The system successfully replicated submicron - 10 micron patterns. The phenomena of laser heating and cooling of the polymer surface by finite element method. It is clarified that high power density and short irradiation time resulted in high replication speed. Furthermore, an antireflection structure and light extraction structures were replicated and their optical properties were investigated.
