| Outline of Final Research Achievements |
Transition spectra and local structures around rare-earth ions are examined by experiments and theoretical calculations to understand the energy transfer associated with electron transition in host-rare earth system of luminescent materials during excitation and emission process. Rare-earth sites that contribute to emission or absorption are identified, and constituent ion arrangements that influence spectrum changes are discussed. Host oxide composition for scintillator material and the preparing process for transparent polycrystalline are proposed.
