Preparation and Luminescence Properties of Eu 2+ and Mn 2+ Coactivated Tricalcium Phosphate Phosphors
Eu 2+ and Mn 2+ coactivated β– Ca 3 ( PO 4 ) 2 ( TCP ) phosphors have been prepared by high‐temperature solid‐state reaction. The site occupation and photoluminescence properties of Eu 2+ and Mn 2+ have been identified and discussed in detail. The energy transfer from Eu 2+ to Mn 2+ in TCP : Eu 2+ ,...
