Muto, S. Sato, K.; Ishikawa, Y.; Bosman, M.; Ishii, Y.; Kawasaki, S.

Luminescent materials widely used for optical devices, such as light-emitting-diode, plasma display and liquid crystal display rely on the inner-shell transition of rare earth (RE) elements. Unstable RE supply, however, accelerates the importance for developing RE-free luminescent materials.
