[en] The luminescence of (Eu³⁺, Ce³⁺ and Eu²⁺) doped apatitic phosphosilicates is studied at either 300 and 77 K. Samples of Ca₅La₅(SiO₄)₃(PO₄)₃O₂:Ln(2%) where Ln=Eu³⁺, Ce³⁺ and Eu²⁺, were synthesized by solid-state reaction at high temperature (1400 deg. C) and then identified by the X-ray diffraction method. The rare-earth cations were found to occupy two cationic sites labeled M(I) and M(II) with a local symmetry C₃ and C_s, respectively. In comparison with Ce³⁺ or Eu²⁺-doped apatitic phosphates, the bands observed in the emission spectra of Ca₅La₅(SiO₄)₃(PO₄)₃O₂:Ce³⁺(2%) and Ca₅La₅(SiO₄)₃(PO₄)₃O₂:Eu²⁺(2%) were found to be shifted to higher wavelength
