| Outline of Final Research Achievements |
Lanthanide semiconductor nanoparticles shows effective opt-magnetic properties, Faraday rotation, which is 100 times larger than that of inorganic glass including Tb(III) ions for optical isolator.
In this study, large Faraday rotation of new Lanthnaide semiconductor nanoparticles with Tb(III) ions was successfully observed for the first time. Using opto-magnetic measurements with photo-irradiation of lanthanide semiconductor nanoparticles and lanthanide clusters, We also found that the opto-magnetic phenomena (Faraday effect) was strongly depended on the electronic state of orbital in lanthanide nanoparticles.
