Abstract

Single crystals of NaEu₉(SiO₄)^₆O^₂, Na_1.5Eu_8.5(SiO₄)₆OF, Na_1.64Gd_8.36(SiO₄)₆O_0.72F_1.28, Gd_9.34(SiO₄)₆O₂, Ca_2.6Eu_7.4(SiO₄)₆O_1.4F_0.6, Ca_4.02Sm_5.98(SiO₄)₆F₂, and K_1.32Pr_8.68(SiO₄)₆O_1.36F_0.64 and powders of NaEu₉(SiO₄)₆O₂, Na_1.5Eu_8.5(SiO₄)₆OF, Eu_9.34(SiO₄)₆O₂, and Gd_9.34(SiO₄)₆O₂ were synthesized via flux growth in selected alkali-fluoride melts. All of the compounds adopt the apatite structure with space group P6₃/m. Luminescence and magnetic data were collected on NaEu₉(SiO₄)₆O₂, Na_1.5Eu_8.5(SiO₄)₆OF, Eu_9.34(SiO₄)₆O₂, and Gd_9.34(SiO₄)₆O₂. Luminescent data indicate that changing the cations and anions that surround the lanthanide site does not change the luminescent properties, making apatites versatile structures for optical materials.
