Outline of Final Research Achievements

Nanofiber is a nanostructured material whose diameter is several tens to several hundreds of nanometers. Applications of nanofibers are not limited to conventional filter cloths and medical filters, and research is progressing widely in the fields of optics and electronics. In this study, we have demonstrated that a dye-doped polymer film covered with electrospun nanofibers exhibits luminescence enhancement.

Academic Significance and Societal Importance of the Research Achievements

LEDは、白熱電球に比べて1/10まで低消費電力になり、エネルギー効率向上に大きな変革を与えた。発光効率の改善は、実用上も非常に重要な問題である。発光素子の発光効率は、材料開発以外にも表面形状の工夫によっても改善することができる。本研究では、ナノファイバーを発光素子の表面に形成することで発光効率がどのように変化するかを詳細に調べ、ナノファイバーの光学応用の知見を得た。
