'PROCESS FOR PRODUCING QUANTUM SPLITTING PHOSPHORS AND NOVEL COMPOSITIONS'

摘要

Quantum splitting phosphors with host lattices activated by praseodymium +3 where covalency of the Pr+3-ligand bond is maintained so that the center of gravity of the Pr+3 4f5d band level is located above the 1So level and the host lattice has a band gap of greater than about 5eV.
