| Outline of Final Research Achievements |
In this study, we synthesized glass phosphors by changing a raw material of an rare-earth ion and a composition of a matrix glass systematically. And luminescence properties of samples were measured. We also investigated a relationship between a local structure around the rare-earth ion and a glass structure of the matrix glass.
It was revealed that a phonon energy of the matrix glass and that around the rare-earth ion influence luminescence properties. Although the relationship between the local structure around the rare-earth ion and the glass structure of the matrix glass was not found, it was indicated that a size of a void and a distribution of the void in the matrix glass affect luminescence properties.
