Redrawn from Hasegawa, T., Kim, S.W., Ishigaki, T., Uematsu, K., Takaba, H., Toda, K., Sato, M., 2014. Novel reddish yellow-emitting Ce3+-doped Ba3Sc4O9 phosphors for blue-light-based white LEDs. Chem. Lett. 43, 828–830. a 3D network, in which activator Ce3+ ions preferably occupy the Sc3+ sites. Rietveld refinement analysis, based on the structural data of Ba3Sc4O9 (ICSD #20621) and Ba3Lu4O9 (ICSD #38383) (ICSD, Inorganic Crystal Structure Database, 2015), confirms that the ScO6 octahedron is slightly distorted from a regular octahedron with the distance Sc–O of 0.1739 nm. Ba3(Sc1xCex)4O9 with x 1⁄4 0.001 shows the highest emission intensity (Fig. 21). The excitation spectrum consists of a relatively narrow band Normalized intensity (a.u.)PDF Image | HANDBOOK ON THE PHYSICS AND CHEMISTRY OF RARE EARTHS
