Effects of Sn2+ Co-Doping on the Photoluminescence of Eu3+ Ion in Strontium Phosphate

Article Preview

The emission of Sn2+ ion can vary from blue to red depending on its co-ordination number in the host lattice. Since Sn2+ ion has strong absorption in the ultra-violet region and can act as a reducing agent, it is of interest to examine the effects of co-doping Sn2+ ions on the luminescence properties of Eu3+ ions in different inorganic phosphor materials. In the present work, Eu3+ and Sn2+ ions co-doped strontium phosphate phosphors were synthesized via a solid-state reaction method in air, argon and reducing atmosphere. The prepared samples were characterized via X-ray diffraction. It was observed that the prepared Eu3+-doped strontium phosphate phosphor material had enhanced Eu3+ emission upon excitation with 395 nm light.
