title: Luminescence properties of Ce3+in orthosilicate oxyapatite NaY9(SiO4)6O2.
abstract: Ce3+-doped orthosilicate oxyapatite NaY9(SiO4)6O2phosphors NaY9-x(SiO4)6O2:xCe3+were prepared by a conventional high-temperature solid-state reaction method, and their spectroscopic characteristics were systematically investigated. The occupancies of Ce3+ions at two different sites (Wyckoff 6 h and 4f sites) in NaY9(SiO4)6O2were determined. The influence of doping concentration on the emission intensity of Ce3+was investigated and the critical distance Rc was estimated in terms of the concentration quenching data.
