    Systematic studies on Sr4La6(SiO4)6M2:Eu3+ (M = F/Cl) phosphors: effects of the halogen anions on photoluminescence

    We successfully prepared Sr4La6(SiO4)6F2:Eu3+ (SLSOF:Eu3+) and Sr4La6(SiO4)6Cl2:Eu3+ (SLSOC:Eu3+) oxyapatite phosphors via the traditional solid-state method. The phosphors’ structure and photoluminescence proper...
