摘要: Abstract Ce3+ and Tb3+ activated fluoro-apatite Ca6La2Na2(PO4)6F2 with chemical formulas Ca6La2−xLnxNa2(PO4)6F2 (Ln = Ce3+, Tb3+) were prepared by a solid state reaction technique at high temperature, their ultraviolet (UV)–visible spectroscopic properties investigated. The results indicate that ions show emission broad band ∼345 nm, while exhibit intense absorption range characteristical green-emitting. In addition, the efficient energy transfer from to in co-doped samples observed discussed.
