Abstract
In white-LED application, the development of novel phosphors with high luminescence efficiency and high-emission color purity is extremely important because the performance of white LEDs is directly affected by the luminescence properties of the phosphors. In this chapter, therefore, we review some Eu2+- and Ce3+-activated phosphor materials and discuss the luminescence properties of these phosphors from the viewpoint of the relationship between the emission-band position and the crystallographic environment including the local site symmetry of the dopant site in the host lattice. We also propose a material-design concept to develop long wavelength-emission phosphors.
