| Outline of Final Research Achievements |
In this project,we have successfully synthesized rare-earth oxides glasses that were regarded glass-forming compositions, obtained optical properties, and performed structural analyses of the glasses.
By using containerless processing, we have obtained La2O3-rich La2O3-Nb2O5 glass systems and La2O3-B2O3 glass systems. Both of the glasses showed excellent optical properties such as refractive index greater than 1.9 with very low wavelength dispersion. Optical parameters and structural information obtained from physical data and structural analysis indicated that the rare-earth rich glasses were totally different from conventional network-forming glasses in the origin of the properties.
