摘要：
Strontium and strontium calcium aluminates and lanthanum and lanthanum magnesium borates activated with Pr 3+ and Mn 2+ exhibit characteristics of quantum-splitting phosphors. Improved quantum efficiency may be obtained by further doping with Gd 3+ . Refined rules for designing quantum-splitting phosphors include the requirement of incorporation of Gd 3+ and Mn 2+ in the host lattice for facilitation of energy migration.
