The luminescence of the Eu3+ ion in the fluorapatite Sr10F2(PO4)6, prepared by solid state reaction and by coprecipitation, is reported. For low amounts of Eu3+, the ion is incorporated into the C(s) site of the structure. Some extra emissions are also observed, due to the substitution of O2- and OH- for F-. Due to this fact, five sites for Eu3+ are thus optically detected and chemically characterized.
