Abstract
Large increases in the efficiency of the conventional P1 phosphor (Zn2SiO4 : Mn) have been achieved by substituting various combinations of III and V oxides for SiO2, e.g., Zn2−yMnySi1−2xAlxPxO4. The photoluminescence efficiency of these phosphors exhibit strong dependence on the AlPO4 substitution concentration x having highest efficiency for x=0.5–1.5%. Cathodoluminescence and decay measurements show that such materials can have CL efficiency greater than the commercial zinc silicates and still have comparable persistence characteristics.Keywords
