Efficiency enhancement in manganese-doped zinc silicate phosphor with AlPO4 substitution

View publication

Abstract

Large increases in the efficiency of the conventional P1 phosphor (Zn 2SiO4: Mn) have been achieved by substituting various combinations of III and V oxides for SiO2, e.g., Zn 2-yMnySi1-2xAlxPxO 4. 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.
