Formation of international collaborative network for establishment of novel light energy conversion technology using optical anisotropy

Project Gist

International collaborative research for development of novel polarization conversion materials generating high purity CP light from unpolarized light


circularly polarized light, polarization conversion, chirality, transparent film

Background and Purpose

Recently, improvement of photoelectric conversion efficiency on photovoltaics by inverse Faraday effect occurred by irradiation of circularly polarized (CP) light have been attracted worldwide attention. In this project, we studied CP conversion film generating high purity CP light from unpolarized light through international collaborative research.

Project Achievements

Through this project, we have established the novel approach, as called luminescence-based CP convertor, enables to exhibit high polarization degree and high light intensity, which was difficult to achieve with existing approaches. In addition to the paper we published on luminescence-based CP convertor, we also got research fundings (KAKENHI, A-STEP, etc.). Furthermore, students (PJ members) have obtained their own research fundings (one internal and one external) by themselves, leading to further acceleration of international collaborative research activities.

Future Prospects

We will aim to further develop international collaborative research involving students from both sides by utilizing the research results and human networks obtained through the support of this project.
