Outline of Final Research Achievements

Crystals of co-doped lanthanide oxyhydroxide were synthesized by the method we had developed and their crystallographic and luminescence properties were characterized. The luminescence color under ultraviolet irradiation shifted with the composition change including the yellow region and the emission intensity under specific irradiation increased significantly by co-doping. These materials are considered good representatives of new phosphors for unique applications. Moreover, co-doped oxides crystals were synthesized by the same method as oxyhydroxide crystals and their infrared to visible upconversion luminescence properties were investigated.
